Resonance propagation and threshold singularities

Primary tabs

Lucio M., J.L. Pestieau, Jean [UCL]

(eng) We consider the problem of propagation of an unstable particle in the framework of Quantum Field Theory. Using unitarity, we show that a real renormalization constant free of threshold singularities naturally arises. Comment: 5 pages, no figures, revtex
