Our picture of the electroweak interactions continues to improve, with ever more precise constraints on the masses of the Higgs boson(s) and on non-standard physics. Some recent developments include: (a) a calculation of higher-order effects on the weak mixing angle which reduces scheme-dependence, (b) a long-awaited improvement in the experimental accuracy of measurement of parity violation in...

The new physics sensitivity of a variety of low-energy parity-violating (PV) observables is analyzed. A comparison is made between atomic PV for a single isotope, atomic PV using isotope ratios, and PV electron-hadron and electron-electron scattering. The complementarity among these observables, as well as with high-energy processes, is emphasized. Theoretical uncertainties entering the interpr...

We reexamine the contact interaction hypothesis for excess high-Q events seen at HERA in ep → eX scattering. We consider the most general structure of contact interactions insisting on SU(3)C×SU(2)L×U(1)Y invariance. Apart from constraints for ee → qq̄ , Drell-Yan and atomic parity violation experiments, we find stringent constraints from neutrino deep inelastic data, provided one assumes lepton...

We discuss CP violation in the context of the minimal SUSY extension of the standard model as well as in a generic low-energy SUSY model. After analyzing the SUSY contributions to the observed CP violation in the kaon system, we emphasize the prospects for disentangling SUSY loop contributions from pure SM effects in B physics.
