Using a functional formalism, we investigate the effect of radiative corrections on the possibility of spontaneous symmetry breaking. We find that in some models, in particular, massless gauge… (More)

This is an article intended for publication in Physics Today. ∗Work supported by Department of Energy contract DE–AC03–76SF00515. We live in a Universe dominated by matter, containing very little… (More)

We discuss the physics of CP violation. The Standard Model predictions for CP violation in B physics are reviewed. A program of studies of neutral B decays that can test the Standard Model… (More)

This talk briefly reviews three types of time-asymmetry in physics, which I classify as universal, macroscopic and microscopic. Most of the talk is focussed on the latter, namely the violation of… (More)

We analyse a class of Grand-Unified Theories and show that, if one accepts severe fine-tuning of many parameters, it is possible to satisfy all the physical constraints that one would like to impose… (More)

This paper discusses the theoretical basis of variational algorithms for thinning degrees of freedom in a lattice Hamiltonian theory. We show that such a thinning can--in principle--be an exact… (More)

This paper examines the operator product using the example of scalar field theories with unstable vacuua. We find that an operator product expansion about the unstable vacuum, with the additional… (More)

We suggest a novel method to determine the sign of cos 2β in the decays B → ψK, by creating interference betweenKL andKS final states via “regeneration,” that is propagation through a matter target… (More)

These lectures are intended as an introduction to flavor physics for graduate students in experimental high energy physics. In these four lectures the basic ideas and of the subject and some current… (More)
