Grand unified theories, in which the strong and electroweak interactions are embedded into
an underlying theory with a single gauge coupling constant, are reviewed. A detailed …

The muon anomalous magnetic moment is one of the most precisely measured quantities in
particle physics. In a recent experiment at Brookhaven it has been measured with a …

Differential geometry and topology have become essential tools for many theoretical
physicists. In particular, they are indispensable in theoretical studies of condensed matter …

A new mathematical framework for the Wess-Zumino chiral effective action is described. It is
shown that this action obeys an a priori quantization law, analogous to Dirac's quantization …

The Higgs Hunter's Guide is a definitive and comprehensive guide to the physics of Higgs
bosons. In particular, it discusses the extended Higgs sectors required by those recent …

We explore the implications for hadron spectroscopy of the" standard" gauge model of weak,
electromagnetic, and strong interactions. The model involves four types of fractionally …

It is shown that in certain parity-violating theories in 4k+ 2 dimensions, general covariance is
spoiled by anomalies at the one-loop level. This occurs when Weyl fermions of spin-1 2 or-3 …

Many numerical predictions of experimental phenomena in particle physics are made
possible by exploiting the discovery that simplifications can happen when phenomena are …

In this paper we use the AdS/CFT correspondence to refine and then establish a set of old
conjectures about symmetries in quantum gravity. We first show that any global symmetry …

It is shown that the path-integral measure for gauge-invariant fermion theories is not
invariant under the γ 5 transformation and the Jacobian gives rise to an extra phase factor …
