Pion productions by proton and Helium-3 on Au197 target at beam energies of 2.8, 5, 10 and 16.587 GeV/nucleon
Abstract
Based on a Relativistic Boltzmann-Uehling- Uhlenbeck transport model, proton and 3He induced reactions on 197Au target at beam energies of 2.8, 5, 10 and 16.587 GeV/nucleon are studied. It is found that compared with proton induced reactions, 3He induced reactions give larger cross sections of pion production, about 5 times those of the proton induced reactions. And more importantly, pion production from 3He induced reaction is more inclined to low-angle emission. Neutrino production via positively charged pion is also discussed accordingly.
