This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Multiboson-production processes like triple-W-boson production are sensitive to triple and quartic gauge couplings and Higgs boson exchanges. They provide a window to investigate electroweak symmetry breaking and are important processes to test the validity of the Standard Model. In the given work, next-to-leading-order (NLO) electroweak (EW) and NLO QCD corrections to WWW production in proton-proton collisions have been worked out for integrated and differential cross sections. This has been done in three different and independent ways: a calculation with on-shell, i.e. stable W bosons, a full off-shell calculation with leptonically decaying W bosons, and a calculation in the triple-pole approximation (TPA), which only takes into account the leading pole term in a threefold resonance expansion. Owing to significant quark-photon-induced EW corrections and due to large photon-PDF uncertainties in the past, the impact of different PDF sets including QED corrections is investigated for on-shell WWW production. For each calculation, the NLO corrections are dominated by QCD corrections and a strong cancellation among the quark-antiquark- and quark-photon-induced EW corrections is observed. The dominant theoretical uncertainty arises from the residual scale dependence. The TPA performs well for integrated cross sections and angular and rapidity distributions. Phase-space regions that are sensitive to off-shell effects and for which the TPA, therefore, is insufficient can be identified based on the results of the TPA calculation alone

Download or read book Proton antiproton Collider Physics written by G. Altarelli and published by World Scientific. This book was released on 1989 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the physics studied at the CERN proton-antiproton collider during its first phase of operation, from the first physics run in 1981 to the last one at the end of 1985.The volume consists of a series of review articles written by physicists who are actively involved with the collider research program. The first article describes the proton-antiproton collider facility itself, including the antiproton source and its principle of operation based on stochastic cooling.The subsequent six articles deal with the various physics subjects studied at the collider. Each article describes in detail the experimental results on a particular subject, and also provides the theoretical framework necessary for their interpretation. Finally the last two articles discuss the physics expectations from the improved collider (the so-called ACOL program, which has just started operation), and also from the next generation of ?supercolliders? which are being considered both in Europe and in the United States America.

Book excerpt: We compute the total cross-section for direct Higgs boson production in hadron collisions at NNLO in perturbative QCD. A new technique which allows us to perform an algorithmic evaluation of inclusive phase-space integrals is introduced, based on the Cutkosky rules, integration by parts and the differential equation method for computing master integrals. Finally, we discuss the numerical impact of the [Omicron]([alpha]{sub s}2) QCD corrections to the Higgs boson production cross-section at the LHC and the Tevatron.

Available in PDF, EPUB and Kindle. Book excerpt: A fully differential calculation of the next-to-leading order QCD corrections to the production of Z-boson pairs in association with a hard jet at the Tevatron and LHC is presented. This process is an important background for Higgs particle and new physics searches at hadron colliders. We find sizable corrections for cross sections and differential distributions, particularly at the LHC. Residual scale uncertainties are typically at the 10% level and can be further reduced by applying a veto against the emission of a second hard jet. Our results confirm that NLO corrections do not simply rescale LO predictions.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the Proceedings of the 17th Workshop of the INFN ELOISATRON Project on "QCD at 200 TeV", held at the "Ettore Majorana" Centre for Scientific Culture, EMCSC, Erice, Trapani, Italy, in the period 11-17 June 1991. The new multi-Te V frontiers of Subnuclear Physics are no more beyond our imagination. A conceptual design of the highest energy (100+100 TeV) proton-proton collider -the ELOISA TRON -already exists. Intensive R & D studies are on the go to develop the most promising and innovative detector technologies for the highest energy and luminosity. QCD (Quantum Chromo-Dynamics) will be the theory to describe the expected Physics scenario of future S upercolliders. The purpose of the Workshop was therefore to review the recent status of QCD in High Energy interactions and to discuss the novel aspects of Perturbative and Non Perturbative QCD with special emphasis on future experimental studies at Super-High Energy Colliders, up to the 200 Te V limit. The topics were: - Classical QCD: particle multiplication, multiplicities and spectra, jet profiles, coherence effects, etc. - Hadron interaction cross-sections and structure functions at Super-High Energies, small-x behaviour, QCD Pomeron, "hot spots"--QCD fragmentation models, present and future. - Artificial neural networks in High Energy Physics. - New theoretical aspects of QCD at Super-High Energies (instanton-induced large cross sections, baryon number violation and peculiar multi-quark production events, etc.)

Available in PDF, EPUB and Kindle. Book excerpt: The recent observation of the Higgs boson has been hailed as the scientific discovery of the century and led to the 2013 Nobel Prize in physics. This book describes the detailed science behind the decades-long search for this elusive particle at the Large Electron Positron Collider at CERN and at the Tevatron at Fermilab and its subsequent discovery and characterization at the Large Hadron Collider at CERN. Written by physicists who played leading roles in this epic search and discovery, this book is an authoritative and pedagogical exposition of the portrait of the Higgs boson that has emerged from a large number of experimental measurements. As the first of its kind, this book should be of interest to graduate students and researchers in particle physics.
