Non-perturbative quark production and transport in the evolving glasma: the WAGASHI event generator
Nicholas J. Benoit, Chiho Nonaka, Hidetoshi Taya
We study non-perturbative quark-antiquark pair production and the subsequent quark dynamics in the earliest glasma stage of relativistic heavy-ion collisions. For that, we develop…
