高能质子和氘核碰撞为研究各种物理效应提供了一个极好的工具，包括原子核中部分子分布函数的修改、胶子饱和度以及核环境中的颜色中和和强子化等。所有这些效应预计都显着依赖于核目标的尺寸和碰撞的撞击参数，也称为碰撞中心性。在本文中，我们详细介绍了一种通过向后快速（即核运动方向）削减多重性来确定 p(d) + A 碰撞中中心性类别的方法，并确定该过程中的系统不确定性。对于根 s(NN) = 200 GeV 处的 d + Au 碰撞，我们发现通过测量来自氘核的中子不与原子核相互作用的事件的比例来确认与几何的联系。作为一种应用，我们考虑核修饰因子 Rp(d)+A，由于感兴趣的过程与后向快速多重性之间的自相关性，测量的中心依赖产率存在偏差。我们在此框架内确定偏差校正因子。使用HIJING蒙特卡罗生成器进一步测试了该方法。我们发现，对于根 s(NN) = 200 GeV 处的 d + Au 碰撞，这些偏差校正很小，并且变化小于 5% (10%)，直至 p(T) = 10 (20) GeV/c。相比之下，对于 v root s(NN) = 5.02 TeV 处的 p + Pb 碰撞，我们发现这些偏差因子要大一个数量级，并且强烈依赖 pT，可能归因于多部分相互作用的更大影响。
High-energy proton- and deuteron-nucleus collisions provide an excellent tool for studying a wide array of physics effects, including modifications of parton distribution functions in nuclei, gluon saturation, and color neutralization and hadronization in a nuclear environment, among others. All of these effects are expected to have a significant dependence on the size of the nuclear target and the impact parameter of the collision, also known as the collision centrality. In this article, we detail a method for determining centrality classes in p(d) + A collisions via cuts on the multiplicity at backward rapidity (i.e., the nucleus-going direction) and for determining systematic uncertainties in this procedure. For d + Au collisions at root s(NN) = 200 GeV we find that the connection to geometry is confirmed by measuring the fraction of events in which a neutron from the deuteron does not interact with the nucleus. As an application, we consider the nuclear modification factors Rp(d)+A, for which there is a bias in the measured centrality-dependent yields owing to auto correlations between the process of interest and the backward-rapidity multiplicity. We determine the bias-correction factors within this framework. This method is further tested using the HIJING Monte Carlo generator. We find that for d + Au collisions at root s(NN) = 200 GeV, these bias corrections are small and vary by less than 5% (10%) up to p(T) = 10 (20) GeV/c. In contrast, for p + Pb collisions at v root s(NN) = 5.02 TeV we find that these bias factors are an order of magnitude larger and strongly pT dependent, likely attributable to the larger effect of multiparton interactions.
