Book Description

Radiative Corrections


Book Description

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.







Particle Phenomenology In The 90's - Proceedings Of The Workshop In High Energy Physics Phenomenology Ii


Book Description

Second in a series of international workshops in high energy physics, WHEPP II dealt with front- line areas of particle phenomenology with an eye to new physics with planned accelerators. Among the topics discussed were: (a) collider physics and structure functions, (b) B physics, hadronic matrix elements and lattice results, (c) new particle search and model building, (d) LEP results and radiative corrections to electro-weak processes and (e) baryon number violation in electroweak processes.




Gauge Theories in Particle Physics: A Practical Introduction, Fourth Edition - 2 Volume set


Book Description

The fourth edition of this well-established, highly regarded two-volume set continues to provide a fundamental introduction to advanced particle physics while incorporating substantial new experimental results, especially in the areas of CP violation and neutrino oscillations. It offers an accessible and practical introduction to the three gauge theories included in the Standard Model of particle physics: quantum electrodynamics (QED), quantum chromodynamics (QCD), and the Glashow-Salam-Weinberg (GSW) electroweak theory. In the first volume, a new chapter on Lorentz transformations and discrete symmetries presents a simple treatment of Lorentz transformations of Dirac spinors. Along with updating experimental results, this edition also introduces Majorana fermions at an early stage, making the material suitable for a first course in relativistic quantum mechanics. Covering much of the experimental progress made in the last ten years, the second volume remains focused on the two non-Abelian quantum gauge field theories of the Standard Model: QCD and the GSW electroweak theory. A new chapter on CP violation and oscillation phenomena describes CP violation in B-meson decays as well as the main experiments that have led to our current knowledge of mass-squared differences and mixing angles for neutrinos. Exploring a new era in particle physics, this edition discusses the exciting discovery of a boson with properties consistent with those of the Standard Model Higgs boson. It also updates many other topics, including jet algorithms, lattice QCD, effective Lagrangians, and three-generation quark mixing and the CKM matrix. This revised and updated edition provides a self-contained pedagogical treatment of the subject, from relativistic quantum mechanics to the frontiers of the Standard Model. For each theory, the authors discuss the main conceptual points, detail many practical calculations of physical quantities from first principles, and compare these quantitative predictions with experimental results, helping readers improve both their calculation skills and physical insight.




Gauge Theories in Particle Physics, 40th Anniversary Edition: A Practical Introduction, Volume 2


Book Description

The fifth edition of this well-established, highly regarded two-volume set continues to provide a fundamental introduction to advanced particle physics while incorporating substantial new experimental results, especially in the areas of Higgs and top sector physics, as well as CP violation and neutrino oscillations. It offers an accessible and practical introduction to the three gauge theories comprising the Standard Model of particle physics: quantum electrodynamics (QED), quantum chromodynamics (QCD), and the Glashow-Salam-Weinberg (GSW) electroweak theory. Volume 2 of this updated edition covers the two non-Abelian gauge theories of QCD and the GSW theory. A distinctive feature is the extended treatment of two crucial theoretical tools: spontaneous symmetry breaking and the renormalization group. The underlying physics of these is elucidated by parallel discussions of examples from condensed matter systems: superfluidity and superconductivity, and critical phenomena. This new edition includes updates to jet algorithms, lattice field theory, CP violation and the CKM matrix, and neutrino physics. New to the fifth edition: · Tests of the Standard Model in the Higgs and top quark sectors · The naturalness problem and responses to it going beyond the Standard Model · The Standard Model as an effective field theory Each volume should serve as a valuable handbook for students and researchers in advanced particle physics looking for an accessible introduction to the Standard Model of particle physics.

An introduction to relativistic processes and the standard model of electroweak interactions


Book Description

The natural framework of high-energy physics is relativistic quantum ?eld theory. This is a complex subject, and it is di?cult to illustrate it in all its aspects within a normal undergraduate course in particle physics, while devoting a su?cient attention to phenomenological aspects. However, in the small-wavelength limit, the semi-classical approximation is, in many cases of practical relevance, accurate enough to provide reliable predictions without entering the technicalities connected with radiative corrections. In particular, in the framework of the semi-classical approximation it is possible to obtain, in alimited number of pages,the expressionsfor relativisticcrosssections and decay rates in a self-contained and rigorous presentation, starting from the basic principles of Quantum Mechanics. Furthermore, even in the case of the standard model of Electroweak Interactions, the construction of the theory in the semi-classical approximation is exhausted by the study of the classical Lagrangian; many di?cult problems, such as those related to the unphysical content of gauge theories, can be dealt with by means of simple prescriptions. Thesearethereasonsthathavedeterminedourchoicetobasetheselecture notes on the semi-classicalapproximationto relativisticquantum ?eld theory. Webelievethatthisapproachleadstoadescriptionofthemostrelevantph- ical processes in high-energy physics, which is adequate to an undergraduate level course on fundamental interactions. Ofcourse,the lackof controlonradiativecorrectionshassomedrawbacks: forexample,theroleofanomalies,andthelimitationstotheHiggsmechanism, cannot be discussed in this context. These issues, however, are beyond the scope of the present text. During the preparation of our manuscript we have bene?ted of the inva- able help and encouragement of Raymond Stora.
