论文摘要
在这些程序中，我们介绍了爱丽丝（Alice）在p $ -pb和pb $ - $ $ pb碰撞中的直接光子和轻中性介子生产的最新结果。在$ \ sqrt {s _ {\ tiny {nn}}} = 5.02 \，\ mathrm {tev} $中，直接的光子过量比$r_γ$ p $ - $ pb碰撞的p $ - $ pb碰撞类别的$r_γ$显示。此外，我们介绍了$ \ sqrt {s _ {\ tiny {nn}}} = 2.76 \，\ mathrm {tev} $。给出了正在进行和将来的测量的前景。
In these proceedings we present the latest results from ALICE on direct photon and light neutral meson production in p$-$Pb and Pb$-$Pb collisions. The direct photon excess ratio $R_γ$ in different charged particle multiplicity classes of p$-$Pb collisions at $\sqrt{s_{\tiny{NN}}}=5.02\,\mathrm{TeV}$ is shown. In addition, we present the direct photon elliptic flow coefficient $v_2$ in central and semicentral events of Pb$-$Pb collisions at $\sqrt{s_{\tiny{NN}}}=2.76\,\mathrm{TeV}$. An outlook on ongoing and future measurements is given.
