The consideration of quantum fields defined on a spacetime lattice provides computational
techniques which are invaluable for studying gauge theories nonperturbatively from first …

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 …

An introduction to explicit <Emphasis Type="Italic">R </Emphasis>-parity violation Page 1
PRAMANA 9 Indian Academy of Sciences Vol. 51, Nos 1 & 2, --journal of July/August 1998 …

These lectures describe in detail the effective Hamiltonians for weak decays of mesons
constructed by means of the operator product expansion and the renormalization group …

We compute the QCD corrections to the decay rate difference in the Bs–B ̄ s system, ΔΓBs,
in the next-to-leading logarithmic approximation using the heavy quark expansion approach …

We provide a comprehensive, up-to-date analysis of possible new physics contributions to
the mass difference Δ MD in D 0-D¯ 0 mixing. We consider the most general low-energy …

We perform a Next-to-Leading order analysis of∆ S= 2 processes beyond the Standard
Model. Combining the recently computed NLO anomalous dimensions and the B …

We point out how, in certain models of new physics, the same combination of couplings
occurs in the amplitudes for both D 0-D¯ 0 mixing and the rare decays D 0→ ℓ+ ℓ-. If the new …

We present a new computation of S-wave color-singlet nonrelativistic QCD matrix elements
for the J/ψ and the η c. We compute the matrix elements of leading order in the heavy-quark …

The real part of ɛ′/ɛ measures direct CP violation in the decays of neutral kaons into two
pions. This is a fundamental quantity that has justly attracted a great deal of theoretical as …
