Fermions, Anomaly and Unitarity in High-Energy Electroweak Scattering
R. Guida, K. Konishi, N. Magnoli
We report the "state of the art" of the problem of violation in high-energy electroweak scatterings. Results of various analyses point toward (though do not prove rigorously…

Level-Crossing in the Instanton-Anti-Instanton Valley
R. Guida, K. Konishi, N. Magnoli
We study the level crossing of the fermion system described by the euclidean Dirac Hamiltonian in the valley background. One chiral fermion level is shown to cross twice the zero v…

Fermions in Instanton Anti-Instanton Background
Riccardo Guida, Kenichi Konishi
We consider the behaviour of fermions in the background of instanton-anti\-instanton type configurations. Several different physics problems, from the high energy electroweak inter…
