PHENIX合作测量了sNN=200 GeV的p+p，p+Al和p+Au碰撞中的高pT双强子相关性。的相关性产生的喷流间和喷流内的相关性，从而在初始和最终状态的非微扰效应的敏感性。垂直于触发强子的关联强子的横动量分量Pout的分布对初态和终态横动量敏感。这些分布作为xE的函数，相关的强子相对于触发强子的纵向动量分数的multidifferentially测量。近侧的Pout宽度，敏感的碎裂横向动量，显示p+Au，p+Al，和p+ p之间没有显着的加宽。远离侧的非微扰Pout宽度被发现在p+Au相比，p+p时加宽;然而，有没有显着的加宽在p+Al相比，p+p碰撞。数据还表明，远离侧的Pout加宽是一个函数的Ncoll，二元核子-核子碰撞的数量，在相互作用。这些结果的初始和最终状态的横动量加宽和能量损失的部分子在一个核中，在其他核效应的潜在影响进行了讨论。© 2019作者。由美国物理学会出版。由SCOAP 3提供资金。（减）

The PHENIX collaboration has measured high-pT dihadron correlations in p+p, p+Al, and p+Au collisions at sNN=200 GeV. The correlations arise from inter- and intrajet correlations and thus have sensitivity to nonperturbative effects in both the initial and final states. The distributions of pout, the transverse-momentum component of the associated hadron perpendicular to the trigger hadron, are sensitive to initial- and final-state transverse momenta. These distributions are measured multidifferentially as a function of xE, the longitudinal momentum fraction of the associated hadron with respect to the trigger hadron. The near-side pout widths, sensitive to fragmentation transverse momentum, show no significant broadening between p+Au, p+Al, and p+p. The away-side nonperturbative pout widths are found to be broadened in p+Au when compared to p+p; however, there is no significant broadening in p+Al compared to p+p collisions. The data also suggest that the away-side pout broadening is a function of Ncoll, the number of binary nucleon-nucleon collisions, in the interaction. The potential implications of these results with regard to initial- and final-state transverse-momentum broadening and energy loss of partons in a nucleus, among other nuclear effects, are discussed. © 2019 authors.
