冷核物质对RHIC J/O2产生的影响:比较遮蔽模型

Cold Nuclear Matter effects on J/ψproduction at RHIC: comparing shadowing models

E. G. Ferreiro, F. Fleuret, J. P. Lansberg, A. Rakotozafindrabe

摘要:

我们提出了一个广泛的研究比较不同的阴影模型和它们对\jpsi生产的影响。我们已经考虑到不同的部分子过程的可能性的$c \bar c$对生产。我们注意到,阴影修正对\jpsi生产的影响显然取决于所考虑的部分子过程。我们的结果进行了比较,在RHIC能量的\dAu碰撞的现有数据。我们尝试不同的打破了截面为每个研究的阴影模型。

英文摘要:

We present a wide study on the comparison of different shadowing models and their influence on \jpsi production. We have taken into account the possibility of different partonic processes for the $c \bar c$-pair production. We notice that the effect of shadowing corrections on \jpsi production clearly depends on the partonic process considered. Our results are compared to the available data on \dAu collisions at RHIC energies. We try different break up cross section for each of the studied shadowing models.
