This book was released on 2016 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here, we compute the next-to-leading order virtual QCD corrections to Higgs-pair production via gluon fusion. We also present analytic results for the two-loop contributions to the spin-0 and spin-2 form factors in the amplitude. The reducible contributions, given by the double-triangle diagrams, are evaluated exactly while the two-loop irreducible diagrams are evaluated by an asymptotic expansion in heavy top-quark mass up to and including terms of O(1/m$8\atop{t}$). We estimate that mass effects can reduce the hadronic cross section by at most 10 %, assuming that the finite top-quark mass effects are of similar size in the entire range of partonic energies.

This book was released on 2020-12-18 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Questo documento riassume lo stato attuale degli ricerche studi, teorici e sperimentali, sulla produzione di coppie di bosoni di Higgs, e sui vincoli, sia diretti che indiretti, al valore del termine di auto-interazione del bosone di Higgs, con l’intento di servire da referenza per i prossimi anni. Il documento discute lo stato degli studi teorici, includendo le più recenti stime della sezione di produzione di coppie di bosoni di Higgs, sviluppi sulle teorie di campo efficaci, e studi su specifici scenari di nuova fisica che possono contribuire alla produzione di due bosoni di Higgs. Sono presentati i più recenti risultati sperimentali sulle ricerche di coppie di bosoni di Higgs e sui limiti diretti e indiretti al termine di auto-interazione, ottenuti al Large Hadron Collider di Ginevra, con una panoramica delle tecniche sperimentali. Infine, sono discusse le capacità dei collisionatori futuri di determinare il termine di auto-interazione del bosone di Higgs. Questo lavoro è iniziato come raccolta di contributi della conferenza “Di-Higgs ai Colliders”, che ha avuto luogo a Fermilab dal 4 al 9 settembre 2018, ma gli argomenti discussi vanno al di là di quelli presentati alla conferenza, includendo ulteriori sviluppi.

Download or read book QCD Corrections to Higgs Pair Production in Bottom Quark Fusion written by and published by . This book was released on 2006 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a complete next-to-leading order (NLO) calculation for the total cross section of inclusive Higgs pair production via bottom-quark fusion (b{bar b} → hh) at the CERN Large Hadron Collider (LHC) in the Standard Model. The NLO QCD corrections lead to less dependence on the renormalization scale ([mu]{sub R}) and the factorization scale ([mu]{sub F}) than the leading-order (LO) cross section, and they significantly increase the LO cross section. The rate for inclusive Higgs pair production is small in the Standard Model, but can be large in models with enhanced couplings of the b quark to the Higgs bosons.
Book Synopsis Higgs Puzzle, The: What Can We Learn From Lep2, Lhc, Nlc, And Fmc? - Proceedings Of The 1996 Ringberg Workshop by : Bernd A Kniehl
Download or read book Higgs Puzzle, The: What Can We Learn From Lep2, Lhc, Nlc, And Fmc? - Proceedings Of The 1996 Ringberg Workshop written by Bernd A Kniehl and published by World Scientific. This book was released on 1997-07-15 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the great success of the standard model of electroweak and strong interactions to describe the phenomena observed in high energy physics experiments, the mechanism by which the elementary particles are endowed with their masses is yet to be unraveled. Does nature choose the Higgs mechanism of spontaneous symmetry breaking as predicted by the standard model, or do we need some alternative explanation? The purpose of the workshop is to capture new trends and ideas in this exciting area of fundamental physics, and to explore the potential of recent (LEPI), present (HERA, LEPII, SLC, Tevatron), and future (FMC, LHC, NLC) colliding-beam experiments to shed light on the Higgs puzzle.

Book Synopsis Precision Tests Of The Standard Electroweak Model by : Paul G Langacker
Download or read book Precision Tests Of The Standard Electroweak Model written by Paul G Langacker and published by World Scientific. This book was released on 1995-02-23 with total page 1032 pages. Available in PDF, EPUB and Kindle. Book excerpt: High precision measurements of weak neutral current and charged current processes and of the properties of the Z and W bosons have established the standard electroweak model as correct down to a distance scale of 10-16 cm, and are a sensitive probe of possible underlying physics. In this book, all aspects of the program are considered in detail, including the structure of the standard model, radiative corrections, high precision experiments, and their implications. The major classes of experiments are surveyed, covering the experiments themselves, the data analysis, results, and prospects.This volume is a detailed reference for theoretical and experimental researchers, as well as an introductory text for advanced students.
Book Synopsis QCD Resummations for Gaugino-pair Hadroproduction by : Jonathan Debove
Download or read book QCD Resummations for Gaugino-pair Hadroproduction written by Jonathan Debove and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weak-scale Supersymmetry (SUSY) is a very well motivated extension of the Standard Model of particle physics. Linking bosons and fermions in an elegant formalism, SUSY allows for a natural solution of the hierarchy problem and for accurate unification of the three Standard Model gauge couplings at a high unification scale. Furthermore, if R-parityis conserved, it provides a convincing candidate for the large amount of cold dark matter observed in the Universe. In the Minimal Supersymmetric Standard Model, this is generally the lightest neutralino, one of the spin-1/2 supersymmetric partners of the electroweak gauge bosons (gauginos) and of the Higgs bosons (Higgsinos), which mix to form four neutral (neutralino) and two charged (chargino) mass eigenstates. After an introduction to supersymmetry, we present the transverse-momentum and threshold resummation formalisms. We then consider the gaugino-pair production at current hadron colliders, i.e. at RHIC, Tevatron and LHC. We study the corresponding effects of polarised initial hadrons and full SUSY-QCD corrections. We finally apply transverse-momentum and threshold re-summations to gaugino-pair production, and show that they have important impact on the transverse-momentum and invariant-mass distributions. Throughout these studies, we also investigate the theoretical uncertainties coming from scale and parton-density function variations.
Book Synopsis Radiative Corrections by : N. Dombey
Download or read book Radiative Corrections written by N. Dombey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Workshop on Radiative Corrections: Results and Perspectives was held at the University of Sussex in fine weather between July 9 and 14 1989. The Workshop was weIl timed: the day after its concluding session the first beam at LEP was circulated. The Original aims of the Workshop were twofold: first to review the existing theoretical work on electroweak radiative corrections in the light of the initial experiments at SLC and LEP, and to attempt to obtain a consensus on the best means of carrying out the calculations of the various processes. This aim became Working Group A on Renormalisation Schemes tor Electroweak Radiative Corrections. The second aim was to review the experimental implementation of radiative corrections and this became Working Group B. Here the problem was to obtain a consensus on the use of Monte Carlo event generators. At the time (March 1987) when Friedrich Dydak wrote to one of us (ND) to suggest a Workshop on the subject of electroweak radiative corrections to take place just before experiments at LEP were to begin, the main theoretical problem was that there was no agreement among theorists on the use of a specific renormalization scheme. Similarly, it was already becoming clear that it was going to be very difficult to compare the experimental results of different groups because they would use different event generators and experimental cuts of their data.
