This book was released on 2002-08-30 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the fourth and last volume of the invaluable publication At the Frontier of Particle Physics: Handbook of QCD. In this volume the reader will find three important sections. The first is devoted to QCD-based phenomenology. It covers issues deeply woven into the fabric of particle physics: weak interactions of light quarks (J Bijnens) and heavy quarkonium physics (A Hoang). The second section is a report on recent advances in the understanding of confinement in three dimensions in the Georgi-Glashow model (I Kogan and A Kovner). The third section deals with lattice QCD (A Kronfeld) and loop equations (A Dubin and Yu Makeenko).The five reviews in Volume 4, together with the 33 reviews in Volumes 1-3, constitute a full encyclopedia, covering all aspects of quantum chromodynamics as we know it today. The articles have been written by recognized experts in this field. Combining features of a handbook and a textbook, this is the most comprehensive source of information on the current status of QCD. It is intended for students as well as physicists — both theorists and experimentalists.

This book was released on 2016-06-15 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the first experimental calibration of the top-quark Monte-Carlo mass. It also provides the top-quark mass-independent and most precise top-quark pair production cross-section measurement to date. The most precise measurements of the top-quark mass obtain the top-quark mass parameter (Monte-Carlo mass) used in simulations, which are partially based on heuristic models. Its interpretation in terms of mass parameters used in theoretical calculations, e.g. a running or a pole mass, has been a long-standing open problem with far-reaching implications beyond particle physics, even affecting conclusions on the stability of the vacuum state of our universe. In this thesis, this problem is solved experimentally in three steps using data obtained with the compact muon solenoid (CMS) detector. The most precise top-quark pair production cross-section measurements to date are performed. The Monte-Carlo mass is determined and a new method for extracting the top-quark mass from theoretical calculations is presented. Lastly, the top-quark production cross-sections are obtained – for the first time – without residual dependence on the top-quark mass, are interpreted using theoretical calculations to determine the top-quark running- and pole mass with unprecedented precision, and are fully consistently compared with the simultaneously obtained top-quark Monte-Carlo mass.

Download or read book Top Quark Pair Production written by Anna Christine Henrichs and published by Springer Science & Business Media. This book was released on 2013-10-04 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before any kind of new physics discovery could be made at the LHC, a precise understanding and measurement of the Standard Model of particle physics' processes was necessary. The book provides an introduction to top quark production in the context of the Standard Model and presents two such precise measurements of the production of top quark pairs in proton-proton collisions at a center-of-mass energy of 7 TeV that were observed with the ATLAS Experiment at the LHC. The presented measurements focus on events with one charged lepton, missing transverse energy and jets. Using novel and advanced analysis techniques as well as a good understanding of the detector, they constitute the most precise measurements of the quantity at that time.

Download or read book Introduction to Soft Collinear Effective Theory written by Thomas Becher and published by Springer. This book was released on 2015-03-04 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among resummation techniques for perturbative QCD in the context of collider and flavor physics, soft-collinear effective theory (SCET) has emerged as both a powerful and versatile tool, having been applied to a large variety of processes, from B-meson decays to jet production at the LHC. This book provides a concise, pedagogical introduction to this technique. It discusses the expansion of Feynman diagrams around the high-energy limit, followed by the explicit construction of the effective Lagrangian - first for a scalar theory, then for QCD. The underlying concepts are illustrated with the quark vector form factor at large momentum transfer, and the formalism is applied to compute soft-gluon resummation and to perform transverse-momentum resummation for the Drell-Yan process utilizing renormalization group evolution in SCET. Finally, the infrared structure of n-point gauge-theory amplitudes is analyzed by relating them to effective-theory operators. This text is suitable for graduate students and non-specialist researchers alike as it requires only basic knowledge of perturbative QCD.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Hadron 05 was to discuss recent developments in hadron spectroscopy. New hadrons have been discovered in the past few years. These states do not quite fit into the traditional quark model classification scheme of hadrons. There has also been a remarkable improvement in the understanding of heavy quark bound systems, or heavy quarkonia, as well as the so-called scalar mesons. Topics covered include baryons, exotics, and hadron structure.

Download or read book Adventure Of The Large Hadron Collider The From The Big Bang To The Higgs Boson written by Daniel Denegri and published by World Scientific. This book was released on 2021-11-08 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the world of quarks and leptons, and of their interactions governed by fundamental symmetries of nature, as well as an introduction to the connection that exists between worlds of the infinitesimally small and the infinitely large.The book begins with a simple presentation of the theoretical framework, the so-called Standard Model, which evolved gradually since the 1960s. The key experiments establishing it as the theory of elementary particle physics, but also its missing pieces and conceptual weaknesses are introduced. The book proceeds with the extraordinary story of the Large Hadron Collider at CERN — the largest purely scientific project ever realized. Conception, design and construction by worldwide collaborations of the detectors of size and complexity without precedent in scientific history are discussed. The book then offers the reader a state-of-the art (2020) appreciation of the depth and breadth of the physics exploration performed by the LHC experiments: the study of new forms of matter, the understanding of symmetry-breaking phenomena at the fundamental level, the exciting searches for new physics such as dark matter, additional space dimensions, new symmetries, and more. The adventure of the LHC culminated in the discovery of the Higgs boson in 2012 (Nobel Prize in Physics in 2013). The last chapter of this book describes the plans for the LHC during the next 15 years of exploitation and improvement, and the possible evolution of the field and future collider projects under consideration.The authors are researchers from CERN, CEA and CNRS (France), and deeply engaged in the LHC program: D Denegri in the CMS experiment, C Guyot, A Hoecker and L Roos in the ATLAS experiment. Some of them are involved since the inception of the project. They give a lively and accessible inside view of this amazing scientific and human adventure.
