Pairproduction in a semiclassical transport theory

Abstract

In high-energy nucleon-nucleon-collisions large meson production rates are observed. As an alternative to meson exchange models here we propose a nonperturbative treatment of the quark-antiquark production from the mean field of colliding nucleon bags. Source terms for particles and antiparticles are developed in a semiclassical quark transport description and the time evolution of the quark density is studied for different mean fields numerically.
