$p$ +Pb与ATLAS碰撞中的矢量玻色子和charmonia测量
Vector boson and charmonia measurements in $p$+Pb collisions with ATLAS
摘要：
电弱玻色子（$Z,γ$和$W$）和charmonia的产生对重离子碰撞的初始态几何和具有潜在核修改的部分子分布函数敏感。由于它们的轻子衰变产物没有强烈的相互作用，它们的运动学不受强相互作用介质的影响，而强相互作用介质可以在重离子碰撞中产生。我们报告的最新结果的ATLAS合作的电弱玻色子和charmonia生产在$p$ +铅碰撞在$\sqrt{s_{\rm NN}} = 5.02$ TeV。在不同的中心性仓中，$Z$和$W$玻色子的产额作为（伪）快度的函数。J/ $ψ$的前向后比是横动量和质心快度的函数。
英文摘要：
The production of electroweak bosons ($Z,γ$ and $W$) and charmonia is sensitive to the initial-state geometry of heavy-ion collisions and to the parton distribution function with its potential nuclear modification. Since their leptonic decay products do not interact strongly, their kinematics are unmodified by the strongly interacting medium, which can be created in a heavy-ion collision. We report on the latest results of the ATLAS Collaboration on electroweak boson and charmonia production in $p$+Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV. Production yields of $Z$ and $W$ bosons are presented as a function of (pseudo-)rapidity in different centrality bins. The forward-backward ratio of J/$ψ$ is shown as a function of transverse momentum and center-of-mass rapidity.
