Upper Limit of the Yield of Di-omega in Central Au-Au Collision at(Snn)1/2=200GeV with HIJING
【摘要】 根据现有的关于(ΩΩ)0+的生成截面的理论计算,利用HIJING事例产生器研究了(Snn)1/2=200GeV下Au- Au中心碰撞中(ΩΩ)0+和(NΩ)022产生过程,分别对(ΩΩ)0+的电磁作用产生过程和两步产生过程中的第一步过程进行了(ΩΩ)0+产率的计算,给出了(ΩΩ)0+产额的上限,对于电磁作用过程,其产率为(1.097±0.293)×10-10 同时我们也对(NΩ)022进行了初步的模拟,初步给出了它的产率为(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 (NΩ)022 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)1/2= 200GeV, while (NΩ)022 is (0.894±0.005)×10-4.
