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 ${}^3$He induced reactions on ${}^{197}$Au 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, ${}^3$He induced reactions give larger cross sections of pion production, about 5 times those of the proton induced reactions. And more importantly, pion production from ${}^3$He induced reaction is more inclined to low-angle emission. Neutrino production via positively charged pion is also discussed accordingly.

5 pages, 11 figures, one figure(fig9) was added to show the scaling behavior of pion production, AMPT calculations were discussed, accepted by PRC
