Radiative corrections to the muon decay spectrum due to soft and virtual electron– positron pairs are calculated.

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...

Nonperturbative self-energy of a bound quark is computed gauge-invariantly in the framework of background perturbation theory. The resulting ∆m 2 q is negative and is a universal function of string tension and current quark mass. The shift of hadron mass squared, M 2 , due to ∆m 2 q is negative, large for light quarks, and solves the long-standing problem of Regge intercepts in relativistic qua...

We explore the mechanism of transverse momentum broadening of fast quarks propagating in nuclei, using Drell-Yan (DY) transverse momentum distributions measured in the experiment E866 at FermiLab with beams of 800 GeV protons. Our theoretical analysis is based on the color dipole approach in the target rest frame, which has provided a successful phenomenological description of a variety of hadr...
