Описание: These lectures concern the properties of topological charge in gauge theories and the physical effects which have been attributed to its existence. No introduction to this subject would be adequate without a discussion of the original work of Belavin, Polyakov, Schwarz, and Tyupkin 1], of the beautiful calculation by 't Hooft 2,3], and of the occurrence of 8-vacua 4-6]. Other important topics include recent progress on solutions of the Yang-Mills equation of motion 7,8], and the problem of parity and time-reversal invariance in strong interactions 9] (axions 10,11], etc. ). In a few places, I have strayed from the conventional line and in one important case, disagreed with it. The im- portant remark concerns the connection between chirality and topological charge first pointed out by 't Hooft 2]: in the literature, the rule is repeatedly quoted with the wrong sign If QS is the generator for Abelian chiral transformations of massless quarks with N flavours, the correct form of the rule is Qs = - 2N {topological charge} (1. 1) where QS means the out eigenvalue of QS minus the in eigenvalue. The sign can be checked by consulting the standard WKB calculation 2,3], rotating to Minkowski space, and observing that the sum of right-handed chiralities of operators in a Green's function equals - QS. The wrong sign is an automatie consequence of a standard but incorrect derivation in which the axial charge is misidentified.

Описание: The articles in this book are written versions of talks presented at a conference organized by the TMR network in Corfu. The main theme of the conference was the interconnection between string theory and gauge theory. These very recent developments draw from many aspects of string theory, supergravity and supersymmetric gauge field theory.

Описание: Offers an introduction to gauge theories and their applications to high-energy particle physics, and takes a look at two new laws of nature-quantum chromodynamics and the electroweak theory. This title examines the logic and structure behind gauge theories and the experimental underpinnings of theories.

Описание: Provides an introduction to gauge field theories formulated on a space-time lattice, and in particular of QCD. This title also provides the reader with the necessary analytical and numerical techniques to carry out research on his own. It introduces the reader to problems which are under intensive investigation.
