D-Au作用J/ψ冷核物质作用快度分布特征的研究
Research on feature of rapidity distribution of J/ψ cold nuclear matter in D-Au interactions
【摘要】 在DKLMT模型基础上,引入描述冷核物质作用的核几何作用函数f(ξ),讨论RHIC能区D-Au碰撞形成单态J/ψ产物机制,给出了核修正因子(RD-Au)随快度的变化关系,并能较好解释RHIC能区的快度分布特征。
【Abstract】 Basing on DKLMT model,we introduce a kind of nuclear geometric interaction function f(ξ)to study the cold nuclear matter(CNM)effects on the color singlet J/ψproduction in D-Au collisions at RHIC.The dependencies of nuclear modification factors(RD-Au)on rapidity are studied.The results are fit well with the experimental data of D-Au interactions at RHIC.
