The formalism necessary to understand the phenomenon of CP nonconservation as
observed in the neutral-kaon system is presented. The distinction between indirect CP …

We review recent results on QCD at finite temperature and non-vanishing baryon number
density. We focus on observables which are of immediate interest to experimental searches …

We use the recently calculated two-loop anomalous dimensions of current-current operators,
QCD and electroweak penguin operators to construct the effective hamiltonian for ΔS= 1 …

We describe a technique for constructing the effective chiral theory for quenched QCD. The
effective theory which results is a Lagrangian one, with a graded symmetry group which …

We extend our Lagrangian technique for chiral perturbation theory for quenched QCD to
include theories in which only some of the quarks are quenched. We discuss the …

I develop a diagrammatic method for calculating chiral logarithms in the quenched
approximation. While not rigorous, the method is based on physically reasonable …

We make a comprehensive study of indirect bounds on scalar leptoquarks that couple
chirally and diagonally to the first generation by examining available data from low-energy …

We present a new calculation of the CP violation parameter ϵ′ ϵ. The results reported in
this paper we have been obtained by using the ΔS= 1 effective hamiltonian computed at the …

An upgraded analysis of ɛ, xd and ɛ′/ɛ, using the latest determinations of the relevant
experimental and theoretical parameters, is presented. Using the recent determination of the …

We compute the magnitude of flavor changing neutral current (FCNC) decays of the t quark
and of the Z boson expected in a two-Higgs doublet model. The charged Higgs boson …
