Book Synopsis Large Hadron Collider Phenomenology by : M. Kramer
Download or read book Large Hadron Collider Phenomenology written by M. Kramer and published by CRC Press. This book was released on 2004-09-30 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the Large Hadron Collider (LHC) under construction and due to come online in 2007, it is appropriate to engage in a focused review on LHC phenomenology. At a time when most of the experimental effort is centered on detector construction and software development, it is vitally important to direct the experimental community and, in particular, new researchers on the physics phenomena expected from the LHC. Large Hadron Collider Phenomenology covers the capabilities of LHC, from searches for the Higgs boson and physics beyond the standard model to detailed studies of quantum chromodynamics, the B-physics sectors, and the properties of hadronic matter at high energy density as realized in heavy-ion collisions. Written by experienced researchers and experimentalists, this reference examines the basic properties and potentials of the machine, detectors, and software required for physics analyses. The book starts with a basic introduction to the standard model and its applications to the phenomena observed at high energy collisions. Later chapters describe the key technological challenges facing the construction of the LHC machine, the operating detectors of the LHC, and the vast computing grid needed to analyze the data. In the final sections, the contributors discuss the quark-gluon plasma (QGP), explore questions and predictions for the LHC program, and examine the physics opportunities of the LHC using information from the forward region. By surveying the difficult challenges of the LHC development while also assessing the novel processes that the LHC will perform, Large Hadron Collider Phenomenology aids less seasoned physicists as well as existing researchers in discovering the numerous possibilities of the LHC.
Book Synopsis Beyond Standard Model Collider Phenomenology of Higgs Physics and Supersymmetry by : Marc Christopher Thomas
Download or read book Beyond Standard Model Collider Phenomenology of Higgs Physics and Supersymmetry written by Marc Christopher Thomas and published by Springer. This book was released on 2016-08-01 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis studies collider phenomenology of physics beyond the Standard Model at the Large Hadron Collider (LHC). It also explores in detail advanced topics related to Higgs boson and supersymmetry – one of the most exciting and well-motivated streams in particle physics. In particular, it finds a very large enhancement of multiple Higgs boson production in vector-boson scattering when Higgs couplings to gauge bosons differ from those predicted by the Standard Model. The thesis demonstrates that due to the loss of unitarity, the very large enhancement for triple Higgs boson production takes place. This is a truly novel finding. The thesis also studies the effects of supersymmetric partners of top and bottom quarks on the Higgs production and decay at the LHC, pointing for the first time to non-universal alterations for two main production processes of the Higgs boson at the LHC–vector boson fusion and gluon–gluon fusion. Continuing the exploration of Higgs boson and supersymmetry at the LHC, the thesis extends existing experimental analysis and shows that for a single decay channel the mass of the top quark superpartner below 175 GeV can be completely excluded, which in turn excludes electroweak baryogenesis in the Minimal Supersymmetric Model. This is a major new finding for the HEP community. This thesis is very clearly written and the introduction and conclusions are accessible to a wide spectrum of readers.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis has been conducted in the context of one of the utmost important searches at current hadron colliders, that is the search for the Higgs boson, the remnant of the electroweak symmetry breaking. We wish to study the phenomenology of the Higgs boson in both the Standard Model (SM) framework and its minimal Supersymmetric extension (MSSM). After a review of the Standard Model in a first part and of the key reasons and ingredients for the supersymmetry in general and the MSSM in particular in a third part, we will present the calculation of the inclusive production cross sections of the Higgs boson in the main channels at the two current hadron colliders that are the Fermilab Tevatron collider and the CERN Large Hadron Collider (LHC), starting by the SM case in the second part and presenting the MSSM results, where we have five Higgs bosons and focusing on the two main production channels that are the gluon gluon fusion and the bottom quarks fusion, in the fourth part. The main output of this calculation is the extensive study of the various theoretical uncertainties that affect the predictions: the scale uncertainties which probe our ignorance of the higher-order terms in a fixed order perturbative calculation, the parton distribution functions (PDF) uncertainties and its related uncertainties from the value of the strong coupling constant, and the uncertainties coming from the use of an effective field theory to simplify the hard calculation. We then move on to the study of the Higgs decay branching ratios which are also affected by diverse uncertainties. We will present the combination of the production cross sections and decay branching fractions in some specific cases which will show interesting consequences on the total theoretical uncertainties. We move on to present the results confronted to experiments and show that the theoretical uncertainties have a significant impact on the inferred limits either in the SM search for the Higgs boson or on the MSSM parameter space, including some assessments about SM backgrounds to the Higgs production and how they are affected by theoretical uncertainties. One significant result will also come out of the MSSM analysis and open a novel strategy search for the Standard Higgs boson at the LHC. We finally present in the last part some preliminary results of this study in the case of exclusive production which is of utmost interest for the experimentalists.
Book Synopsis Perspectives On String Phenomenology by : Gordon Kane
Download or read book Perspectives On String Phenomenology written by Gordon Kane and published by World Scientific. This book was released on 2014-12-23 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The remarkable recent discovery of the Higgs boson at the CERN Large Hadron Collider completed the Standard Model of particle physics and has paved the way for understanding the physics which may lie beyond it. String/M theory has emerged as a broad framework for describing a plethora of diverse physical systems, which includes condensed matter systems, gravitational systems as well as elementary particle physics interactions. If string/M theory is to be considered as a candidate theory of Nature, it must contain an effectively four-dimensional universe among its solutions that is indistinguishable from our own. In these solutions, the extra dimensions of string/M theory are “compactified” on tiny scales which are often comparable to the Planck length. String phenomenology is the branch of string/M theory that studies such solutions, relates their properties to data, and aims to answer many of the outstanding questions of particle physics beyond the Standard Model.This book contains perspectives on string phenomenology from some of the leading experts in the field. Contributions will range from pedagogical general overviews and perspectives to more technical reviews. We hope that the reader will get a sense of the significant progress that has been made in the field in recent years (e.g. in the topic of moduli stabilization) as well as the topics currently being researched, outstanding problems and some perspectives for the future.
Download or read book LHC Phenomenology written by Einan Gardi and published by Springer. This book was released on 2014-08-27 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers a very broad spectrum of experimental and theoretical activity in particle physics, from the searches for the Higgs boson and physics beyond the Standard Model, to detailed studies of Quantum Chromodynamics, the B-physics sectors and the properties of hadronic matter at high energy density as realised in heavy-ion collisions. Starting with a basic introduction to the Standard Model and its most likely extensions, the opening section of the book presents an overview of the theoretical and phenomenological framework of hadron collisions and current theoretical models of frontier physics. In part II, discussion of the theory is supplemented by chapters on the detector capabilities and search strategies, as well as an overview of the main detector components, the initial calibration procedures and physics samples and early LHC results. Part III completes the volume with a description of the physics behind Monte Carlo event generators and a broad introduction to the main statistical methods used in high energy physics. LHC Phenomenology covers all of these topics at a pedagogical level, with the aim of providing young particle physicists with the basic tools required for future work on the various LHC experiments. It will also serve as a useful reference text for those working in the field.

Available in PDF, EPUB and Kindle. Book excerpt: This new book is fully up to date with all the latest developments on both theoretical and experimental investigations of the Standard Model (SM) of particle physics with a particular emphasis on its historical development on both sides. It further stresses the cross-fertilisation between the two sub-disciplines of theoretical and experimental particle physics which has been instrumental in establishing the SM. In other words, the book develops a truly phenomenological attitude to the subject. In addition to emphasising the successes of the SM, this book also critically assesses its limitations and raises key unanswered questions for the purpose of presenting a new perspective of how to further our knowledge above and beyond it. It also contains both historical information from past experiments and latest results from the Large Hadron Collider at CERN. This book will be an invaluable reference to advanced undergraduate and postgraduate students, in addition to early-stage researchers in the field. Key Features: Provides a unique approach not found in current literature in developing and verifying the SM Presents the theory pedagogically but rigorously from basic knowledge of quantum field theory Brings together experimental and theoretical practice in one, cohesive text

Download or read book Higgs Boson Phenomenology Beyond the Standard Model written by Solen Le Corre and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the discovery of the Higgs boson in June 2012 at the Large Hadron Collider, the particle collider located beneath the France-Switzerland border, interest in the study of the scalar sector in elementary particle physics significantly increased. In particular, as the Higgs boson plays a very special role in the Standard Model of particle physics, experimentalists study its properties with great care.The goal of the Standard Model is to describe the interactions between elementary particles. However the theory is not quite complete. Indeed, in addition to some purely theoretical problems, a number of experimental observations cannot be explained by the Standard Model. Theorists are therefore looking for a more comprehensive theory able to fully explain the observations.This thesis is based on the study of the scalar sector of two different extensions of the Standard Model of particle physics. I have worked on the Two-Higgs Doublet Model - this model is purely effective but can be included in more comprehensive theories - as well as on a model based on a combination of Technicolor and Composite Higgs theories in the framework of the SU (4) ? Sp(4) symmetry breaking pattern. I studied the latter via an effective approach but the full theory is able to get rid of some of the pitfalls of the Standard Model.These two models include a scalar sector that is richer than the one found in the Standard Model and contain at least one particle which can be assimilated to the Higgs boson discovered at the LHC.I performed a phenomenological study for these two models and tested them against both theoretical and experimental constraints. In particular I used the latest studies on the 125 GeV Higgs boson and on possible additional scalars performed by the ATLAS and CMS collaborations. The application of all these constraints drastically reduced the available parameter space of the two models. In particular it narrowed the possible mass range of the additional scalars, allowing to know more accurately where to search them experimentally in order to prove or rule out their possible existence.As of today the two theories I worked on are still not excluded by the latest experimentaldata.

Book Synopsis Topics in Particle Phenomenology at LHC by : Yang Gao
Download or read book Topics in Particle Phenomenology at LHC written by Yang Gao and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation gives a number of examples on how to look for certain Beyond Standard Model physics at the Large Hadron Collider (LHC). It points out the exact experimental signatures for either singly produced or pair produced Higgs bosons at the LHC in a Type-I Two Higgs Doublet Model. It is shown that the high luminosity LHC is required to make a discovery of the additional Higgs bosons. In searching for a supersymmetric top partner, a new kinematic variable in the reconstruction of semi-leptonic and di-leptonic decays is proposed. It is shown that this new variable is effective in discerning the top partner in these decay channels.
Book Synopsis Lectures on LHC Physics by : Tilman Plehn
Download or read book Lectures on LHC Physics written by Tilman Plehn and published by Springer. This book was released on 2014-08-05 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the discovery of the Higgs boson, the LHC experiments have closed the most important gap in our understanding of fundamental interactions, confirming that such interactions between elementary particles can be described by quantum field theory, more specifically by a renormalizable gauge theory. This theory is a priori valid for arbitrarily high energy scales and does not require an ultraviolet completion. Yet, when trying to apply the concrete knowledge of quantum field theory to actual LHC physics - in particular to the Higgs sector and certain regimes of QCD - one inevitably encounters an intricate maze of phenomenological know-how, common lore and other, often historically developed intuitions about what works and what doesn’t. These lectures cover three aspects to help understand LHC results in the Higgs sector and in searches for physics beyond the Standard Model: they discuss the many facets of Higgs physics, which is at the core of this significantly expanded second edition; then QCD, to the degree relevant for LHC measurements; as well as further standard phenomenological background knowledge. They are intended to serve as a brief but sufficiently detailed primer on LHC physics to enable graduate students and all newcomers to the field to find their way through the more advanced literature, and to help those starting to work in this very timely and exciting field of research. Advanced readers will benefit from this course-based text for their own lectures and seminars. .

Available in PDF, EPUB and Kindle. Book excerpt: Scope and methods.In this dissertation, I study the theory and phenomenology of Higgs bosons in the framework of various models with supersymmetry, left-right symmetry and universal extra dimensions. In Chapter 1, I summarize the various models studied and motivation for each. Chapter 2 is devoted to the study of Higgs boson mass spectrum in various left-right supersymmetric models with different symmetry breaking sectors. Chapter 3 involves the collider phenomenology of relatively light doubly-charged Higgs bosons and Higgsinos which arise naturally in supersymmetric left-right models. In Chapter 4, I look at the constraints on a minimal universal extra dimensional model from the measured signal strength for Higgs boson decay at the large hadron collider.Findings and conclusions.
Book Synopsis Phenomenology of the Left-right Twin Higgs Model by :
Download or read book Phenomenology of the Left-right Twin Higgs Model written by and published by . This book was released on 2006 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The twin Higgs mechanism was proposed recently to solve the little hierarchy problem. We study the implementation of the twin Higgs mechanism in left-right models. At the TeV scale, heavy quark and gauge bosonsappear, with rich collider phenomenology. In addition, there are extra Higgs bosons, some of which couple to both the standard model fermion sector and the gauge sector, while others couple to the gauge bosons only. We present the particle spectrum and study the general features of the collider phenomenology of this class of model at the Large Hadron Collider.
