We use functional Schroedinger equation techniques, both for [lambda][phi][sup 4] theory (no tunneling) and for [ital B]+[ital L] violation in SU(2) gauge theory, to estimate amplitudes for the decay of one off-shell particle into [ital N] on-shell p

We summarize a series of arguments, based on semi-classical techniques, for calculating fixed-angle scattering amplitudes such as T2→N in a weekly-coupled theory with coupling g2⪡1, and Ng2⩾1. These techniques are applied to the (functional) Sc

Because of the failure of the dilute-instanton-gas approximation (DIGA) at high energies, recent calculations of ({ital B}+{ital L})-violating processes in the standard model show blatant violations of unitarity, and suggest that these processes may

This paper is a continuation of a systematic search for all renormalizable interactions of heavy vector bosons. It is argued that in any renormalizable theory the $S$ matrix must satisfy high-energy unitarity bounds in the tree approximation. In an e

It is suggested that spontaneous breakdown of chiral symmetry in QCD takes place because a special class of gauge-field configurations (``fermion guides'') allow massless quarks to propagate to arbitrarily large distance with an undiminished amplitud

We continue and extend our earlier work on infrared singularities of non-Abelian gauge theories (exemplified by quantum chromodynamics, or QCD), emphasizing the nature of these singularities in space-time rather than in momentum space. The leading lo

A systematic search is made for all renormalizable theories of heavy vector bosons. It is argued that in any renormalizable Lagrangian theory high-energy unitarity bounds should not be violated in perturbation theory (apart from logarithmic factors i
