Available in PDF, EPUB and Kindle. Book excerpt: Precision measurement of the stop mass at the ILC is done in a method based on cross-sections measurements at two different center-of-mass energies. This allows to minimize both the statistical and systematic errors. In the framework of the MSSM, a light stop, compatible with electro-weak baryogenesis, is studied in its decay into a charm jet and neutralino, the Lightest Supersymmetric Particle (LSP), as a candidate of dark matter. This takes place for a small stop-neutralino mass difference.

Book excerpt: Precision measurements have played a vital role in our understanding of elementary particle physics. Experiments performed using e[sup+]e[sup -] collisions have contributed an essential part. Recently, the precision measurements at LEP and SLC have probed the standard model at the quantum level and severely constrained the mass of the Higgs boson[1]. Coupled with the limits on the Higgs mass from direct searches[2], this enables the mass to be constrained to be in the range 115-205 GeV. Developments in accelerator R and D have matured to the point where one could contemplate construction of a linear collider with initial energy in the 500 GeV range and a credible upgrade path to[approx] 1 TeV. Now is therefore the correct time to critically evaluate the case for such a facility. The Working Group E3, Experimental Approaches at Linear Colliders, was encouraged to make this evaluation. The group was charged with examining critically the physics case for a Linear Collider (LC) of energy of order 1 TeV as well as the cases for higher energy machines, assessing the performance requirements and exploring the viability of several special options. In addition it was asked to identify the critical areas where R and D is required (the complete text of the charge can be found in the Appendix). In order to address this, the group was organized into subgroups, each of which was given a specific task. Three main groups were assigned to the TeV-class Machines, Multi-TeV Machines and Detector Issues. The central activity of our working group was the exploration of TeV class machines, since they are being considered as the next major initiative in high energy physics. We have considered the physics potential of these machines, the special options that could be added to the collider after its initial running, and addressed a number of important questions. Several physics scenarios were suggested in order to benchmark the physics reach of the linear collider and persons were appointed to maintain contacts with the relevant activities in the various Physics Working Groups. Special options considered were precision electroweak studies that could be done by running the collider at and near the Z pole (so called Giga Z running); collisions involving[gamma][gamma], e[sup -]e[sup -], or e[gamma] interactions; and positron beam polarization. The following questions were posed in order to focus the discussions: (1) In view of the fact that the luminosity is a function of energy, what are the trade-offs involved in selecting the energy. (2) What is the argument for proceeding with the construction of a Linear collider as soon as possible rather than waiting for data from LHC? (3) In the context of a definite physics scenario, what is a realistic run plan? i.e. How much luminosity at each energy? (4) What should be the initial energy of a linear collider and to what energy should that machine extended?

Download or read book International Linear Collider (ILC) written by Alexey Drutskoy and published by Morgan & Claypool Publishers. This book was released on 2018-11-26 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Linear Collider (ILC) is a mega-scale, technically complex project, requiring large financial resources and cooperation of thousands of scientists and engineers from all over the world. Such a big and expensive project has to be discussed publicly, and the planned goals have to be clearly formulated. This book advocates for the demand for the project, motivated by the current situation in particle physics. The natural and most powerful way of obtaining new knowledge in particle physics is to build a new collider with a larger energy. In this approach, the Large Hadron Collider (LHC) was created and is now operating at the world record center of-mass energy of 13 TeV. Although the design of colliders with a larger energy of 50-100 TeV has been discussed, the practical realization of such a project is not possible for another 20-30 years. Of course, many new results are expected from LHC over the next decade. However, we must also think about other opportunities, and in particular, about the construction of more dedicated experiments. There are many potentially promising projects, however, the most obvious possibility to achieve significant progress in particle physics in the near future is the construction of a linear e+e- collider with energies in the range (250-1000) GeV. Such a project, the ILC, is proposed to be built in Kitakami, Japan. This book will discuss why this project is important and which new discoveries can be expected with this collider.

This book was released on 1996-08-22 with total page 836 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collider experiments have become essential to studying elementary particles. In particular, lepton collisions such as e⁺e⁻ are ideal from both experimental and theoretical points of view, and are a unique means of probing the new energy region, sub-TeV to TeV. It is a common understanding that a next-generation e⁺e⁻ collider will have to be a linear machine that evades beam-energy losses due to synchrotron radiation. In this book, physics feasibilities at linear colliders are discussed in detail, taking into account the recent progress in high-energy physics.

Book Synopsis Electroweak Precision Measurements and Collider Probes of the Standard Model with Large Extra Dimensions by :
Download or read book Electroweak Precision Measurements and Collider Probes of the Standard Model with Large Extra Dimensions written by and published by . This book was released on 1999 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The elementary particles of the Standard Model may live in more than 3+1 dimensions. We study the consequences of large compactified dimensions on scattering and decay observables at high-energy colliders. Our analysis includes global fits to electroweak precision data, indirect tests at high-energy electron-positron colliders (LEP2 and NLC), and direct probes of the Kaluza-Klein resonances at hadron colliders (Tevatron and LHC). The present limits depend sensitively on the Higgs sector, both the mass of the Higgs boson and how many dimensions it feels. If the Higgs boson is trapped on a 3+1 dimensional wall with the fermions, large Higgs masses (up to 500 GeV) and relatively light Kaluza-Klein mass scales (less than 4 TeV) can provide a good fit to precision data. That is, a light Higgs boson is not necessary to fit the electroweak precision data, as it is in the Standard Model. If the Higgs boson propagates in higher dimensions, precision data prefer a light Higgs boson (less than 260 GeV), and a higher compactification scale (greater than 3.8 TeV). Future colliders can probe much larger scales. For example, a 1.5 TeV electron-positron linear collider can indirectly discover Kaluza-Klein excitations up to 31 TeV if 500 fb−1 integrated luminosity is obtained.
Book Synopsis Physics at the Large Hadron Collider by : Amitava Datta
Download or read book Physics at the Large Hadron Collider written by Amitava Datta and published by Springer Science & Business Media. This book was released on 2010-05-30 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an epoch when particle physics is awaiting a major step forward, the Large Hydron Collider (LHC) at CERN, Geneva will soon be operational. It will collide a beam of high energy protons with another similar beam circulation in the same 27 km tunnel but in the opposite direction, resulting in the production of many elementary particles some never created in the laboratory before. It is widely expected that the LHC will discover the Higgs boson, the particle which supposedly lends masses to all other fundamental particles. In addition, the question as to whether there is some new law of physics at such high energy is likely to be answered through this experiment. The present volume contains a collection of articles written by international experts, both theoreticians and experimentalists, from India and abroad, which aims to acquaint a non-specialist with some basic issues related to the LHC. At the same time, it is expected to be a useful, rudimentary companion of introductory exposition and technical expertise alike, and it is hoped to become unique in its kind. The fact that there is substantial Indian involvement in the entire LHC endeavour, at all levels including fabrication, physics analysis procedures as well as theoretical studies, is also amply brought out in the collection.

This book was released on 1997-05-05 with total page 749 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an expanded version of the report by the Electroweak Symmetry Breaking and Beyond the Standard Model Working Group which was contributed to Particle Physics — Perspectives and Opportunities, a report of the Division of Particles and Fields Committee for Long Term Planning. One of the Working Group's primary goals was to study the phenomenology of electroweak symmetry breaking and attempt to quantify the “physics reach” of present and future colliders. Their investigations encompassed the Standard Model — with one doublet of Higgs scalars — and approaches to physics beyond the Standard Model. These include models of low-energy supersymmetry, dynamical electroweak symmetry breaking, and a variety of extensions of the Standard Model with new particles and interactions. The Working Group also considered signals of new physics in precision measurements arising from virtual processes and examined experimental issues associated with the study of electroweak symmetry breaking and the search for new physics at present and future hadron and lepton colliders.This volume represents an important contribution to the efforts being made to advance the frontiers of particle physics.
