Upper Limit of the Yield of Di-Omega in Central Au-Au Collision at Snn=200GeV with HIJING

  • According to the theoretical calculations on the cross section, the (ΩΩ)0+'s production including both the electromagnetic interaction process and the two-step process is studied with HIJING package. The production of the \noo is also simulated and calculated in this paper. The upper limit of the production rate of the (ΩΩ)0+ in the electromagnetic interaction process is (1.097±0.293)×10-10 per central Au-Au collision event at snn=200GeV, while (NΩ)022 is (0.894±0.005)×10-4.

Abstract: According to the theoretical calculations on the cross section, the (ΩΩ)0+'s production including both the electromagnetic interaction process and the two-step process is studied with HIJING package. The production of the \noo is also simulated and calculated in this paper. The upper limit of the production rate of the (ΩΩ)0+ in the electromagnetic interaction process is (1.097±0.293)×10-10 per central Au-Au collision event at snn=200GeV, while (NΩ)022 is (0.894±0.005)×10-4.
