Deuteron production in relativistic heavy ion collisions via stochastic multiparticle reactions
Physical review / C 104(3)
We study the deuteron production via the deuteron pion and nucleon catalysis reactions, πpn ↔ πd and Npn ↔ Nd, by employing stochastic multi-particle reactions in the hadronic transport approach SMASH for the first time. This is an improvement compared to previous studies, which introduced an artificial fake resonance d′ to simulate these 3 ↔ 2 reactions as a chain of 2 ↔ 2 reactions. The derivation of the stochastic criterion for multi-particle reactions is presented in a comprehensive fashiondoi:10.15120/gsi-2022-00139 fatcat:wlofjs2vorc53dx2fekhpejdza
