本文介绍了用大型强子对撞机ATLAS探测器在sqrt[s_{NN}]=5.02 TeV，积分光度为0.49 nb^{-1}的条件下，对Pb+Pb碰撞中γγ→μ^{+}μ^{-}产生的测量结果。测量了μ子之间的方位角和横向动量相关性作为碰撞中心性的函数。μ子对是由γγ通过原子核的大电磁场相互作用产生的。使用模板拟合方法去除μ子对的背景源的贡献。在外围碰撞中，μ子表现出很强的背靠背相关性，与以前测量的超外围碰撞中μ子对的产生一致。角关联被观察到显着扩大中心碰撞。这些修改在质量上与μ子在穿过碰撞中产生的热物质时的再散射一致。
This Letter presents a measurement of γγ→μ^{+}μ^{-} production in Pb+Pb collisions recorded by the ATLAS detector at the Large Hadron Collider at sqrt[s_{NN}]=5.02 TeV with an integrated luminosity of 0.49 nb^{-1}. The azimuthal angle and transverse momentum correlations between the muons are measured as a function of collision centrality. The muon pairs are produced from γγ through the interaction of the large electromagnetic fields of the nuclei. The contribution from background sources of muon pairs is removed using a template fit method. In peripheral collisions, the muons exhibit a strong back-to-back correlation consistent with previous measurements of muon pair production in ultraperipheral collisions. The angular correlations are observed to broaden significantly in central collisions. The modifications are qualitatively consistent with rescattering of the muons while passing through the hot matter produced in the collision.
