Peng and two sets of nuclear parton distribution functions(EKS & HKM),we discuss the energy loss of partons in Drell-Yan process and present that the determinati.
核物质中的能量损失效应是不同于束缚核子部分子分布函数核效应的另外一种核效应,而核Drell-Yan过程是研究这种能量损失效应的最佳途径。
It is found that,considering the spatial dependence of parton distribution functions,the cross-section of nuclear Drell-Yan process changes significantly.
计算结果与未来精确测量p-Au碰撞核Drell-Yan过程的实验数据比较,就能定量的验证部分子分布函数的空间依赖性。
LHC is a Proton-Proton collider whose center-mass-energy comes to 14 TeV, with which one can probe the parton distributions in small x (x ~ 10-6) region when Q1≤10GeV2, so it is important for researching small x physics.
为了预言将来在LHC上可能观测到的实验现象,必须首先预言LHC能区的部分子的分布函数,这是因为必须利用部分子分布函数来计算一些可能发生的物理现象的背景,如Higgs粒子的产生等;部分子分布函数还有利于预言各种反应过程的散射截面。
