论文摘要
我们介绍了LHC上$ PA $碰撞的双Parton散射（DPS）四射流生产截面的预测。依靠实验能力将中心性与质子 - 核碰撞的影响参数$ b $相关联，我们讨论了一种在$ pa $碰撞中提取双方散射贡献的策略，该策略可直接访问核中双方分布。我们表明，通过四个喷气机的DPS的生产横截面，其中两种可能是轻或重型夸克喷气机，足够大，可以允许该方法已与2016年$ PA $运行中累积的数据一起使用。
We present predictions for the double parton scattering (DPS) four-jet production cross sections in $pA$ collisions at the LHC. Relying on the experimental capabilities to correlate centrality with impact parameter $B$ of the proton-nucleus collision, we discuss a strategy to extract the double parton scattering contributions in $pA$ collisions, which gives direct access to double parton distribution in the nucleon. We show that the production cross sections via DPS of four jets, out of which two may be light- or heavy-quark jets, are large enough to allow the method to be used already with data accumulated in 2016 $pA$ run.
