The puzzling observation that deuterons, having a binding energy of only 2.2 MeV, survive final-state temperatures of more than 100 MeV in high-energy heavy-ion collisions, has been explained as a delicate balance between creation and destruction at similar rates. However, because the process involves collisions between more than two particles, one had to use workarounds for a satisfactory description. The authors treat deuteron catalysis from nucleons and pions with stochastic multiparticle reactions, making previous workarounds for collisions between more than two particles obsolete.
