Anomalous Violation of Conservation Laws in Minkowski Space: Spontaneously Broken Gauge Theories
Thomas M. Gould, Stephen D. H. Hsu
We extend our previous results on the evolution of quantum fermi fields in Minkowski gauge field backgrounds to the case of spontaneously broken gauge theories. We obtain a selecti…
Anomalous Violation of Conservation Laws in Minkowski Space
Thomas M. Gould, Stephen D. H. Hsu
We consider the evolution of quantum fermi fields in Minkowski gauge field backgrounds. Our motivation is the study of anomalous fermion number violating processes. We derive selec…
Quantum Scattering and Classical Solutions
Stephen D. H. Hsu
I discuss a formalism for computing quantum scattering amplitudes using a semiclassical expansion of a functional integral representation for the S-matrix. The classical background…
Quantum Scattering from Classical Field Theory
Thomas M. Gould, Stephen D. H. Hsu, Erich R. Poppitz
We show that scattering amplitudes between initial wave packet states and certain coherent final states can be computed in a systematic weak coupling expansion about classical solu…
