论文摘要
我们提出了一种形式主义，用于确定QCD的近质量质子 - 蛋白质和质子较重的离子碰撞，以确定速度迅速的独家重型媒介膜产量（$ j/ψ，υ$）的横截面。我们将$ PP $和$ P $ PB碰撞的生产进行比较和对比，并展示这些过程的数据如何在各种规模的范围内提供有关质子和重离子的低$ x $ gluon分布的信息。
We present a formalism for determining the cross section for exclusive heavy vector meson production ($J/ψ, Υ$) as a function of rapidity, in both high energy proton-proton and proton-heavy ion collisions, at next-to-leading order in QCD. We compare and contrast the production in $pp$ and $p$Pb collisions and show how data for these processes can give information on the low $x$ gluon distribution of the proton and heavy ions at a range of different scales.
