Abstract
We calculate the medium modification factor \({{I}_{{pA}}}\) for 5.02 TeV \(p\) + Pb collisions. We use the Monte Carlo Glauber model to determine the parameters of the quark–gluon plasma fireball in \(pA\) jet events. Our calculations show that the jet quenching effect for \({{I}_{{pA}}}\) turns out to be rather small. We have found that the theoretical \({{I}_{{pA}}}\) as a function of the underlying event charged multiplicity density, within errors, agrees with data from ALICE [1] for 5.02 TeV \(p\) + Pb collisions. However, the experimental errors are too large to draw a firm conclusion on the possible presence of jet quenching.
我们计算了 5.02 TeV p + Pb 对撞的介质修正因子 IpA。我们使用蒙特卡洛格劳伯模型来确定 pA 喷射事件中夸克-胶子等离子体火球的参数。我们的计算表明，IpA 的喷流淬火效应相当小。我们发现，在误差范围内，理论 IpA 作为基本事件带电多重性密度的函数，与 ALICE [1] 5.02 TeV p + Pb 对撞的数据一致。然而，实验误差太大，无法对可能存在的射流淬火得出肯定的结论。
