推广x重新标度模型与核内核子的胶子分布函数

Nuclear Gluon Distributiom in the Extended x-Rescaling Model

利用推广ｘ重新标度模型，并结合考虑核内邻近核子的海夸克和胶子发生空间重叠而在小ｘ区域引起的核遮蔽效应，计算了Ｓｎ和Ｃ核胶子分布函数之比值，所得结果与ＮＭＣ组最新实验数据符合甚好。

Using the extended x-rescaling model and taking account of the nuclear shadowingeffect by the spatial overlap of sea quarks and gluons from neighbouring nucleons in thenucleus in small x region, we calculate the ratios Gsn(x)/Gc(x). The calculated results arein good agreement with recent NMC experimental data
