Mv. Libanov et al., MULTIPARTICLE PROCESSES AND SEMICLASSICAL ANALYSIS IN BOSONIC FIELD-THEORIES, Physics of particles and nuclei, 28(3), 1997, pp. 217-240
The problems associated with multiparticle production in model scaler
theories are discussed. When the number of emitted particles is compar
able to the inverse coupling constant, ordinary perturbation theory is
inapplicable. The possibility of using semiclassical methods to calcu
late the multiparticle cross sections taking into account all importan
t loop corrections is studied. (C) 1997 American Institute of Physics.
