论文摘要
我们研究了在诱发Gluon发射的轻锥路径积分方法中的介质修饰因子$ I_ {PP} $。我们使用运行耦合$α_s(Q,t)$的参数化,该$的高原约为$ q \simκT$。我们使用安装在核修饰因子$ r_ {aa} $的LHC数据的$κ$中,计算$ i_ {pp} $,没有免费参数。我们发现,比率$ i_ {pp}/\ langle i_ {pp} \ rangle $的理论多重性依赖性($ 5.02 $ tev $ pp $ collisions)与爱丽丝(Alice)的最新预赛数据合理地一致。
We study the medium modification factor $I_{pp}$ within the light-cone path integral approach to induced gluon emission. We use parametrization of the running coupling $α_s(Q,T)$ which has a plateau around $Q\sim κT$. We calculate $I_{pp}$ with no free parameters using $κ$ fitted to the LHC data on the nuclear modification factor $R_{AA}$. We find that the theoretical multiplicity dependence of the ratio $I_{pp}/\langle I_{pp}\rangle$ for $5.02$ TeV $pp$ collisions agrees reasonably with the recent preliminary data from ALICE [1].
