重味喷流的产生和与ALICE的相关性

Heavy-flavour jet production and correlations with ALICE

Jakub Kvapil

摘要:

这方面的贡献集中在最新的研究与ALICE探测器执行重味射流。本文介绍了在$\sqrt{s}=5.02$ TeV和$13\ \mathrm{TeV}$的pp碰撞中D介子携带的喷流动量分数的测量结果。将显示与POWHEG+PYTHIA的比较。此外,首次在大型强子对撞机上测量了$\sqrt{s}=13\ \mathrm{TeV}$ pp碰撞中$\mathrm{Λ_c^+}$重子携带的喷流动量分数。在$\sqrt{s}=5.02\ \mathrm{TeV}$的pp碰撞中产生的重味喷流也将用重味强子衰变电子和美强子衰变顶点标记的带电喷流来解决。给出了$\sqrt{s_{\mathrm{NN}}}=5.02\ \mathrm{TeV}$ p-Pb碰撞中重味标记喷流的核修正因子。

英文摘要:

This contribution focuses on the latest studies of heavy-flavour jets performed with the ALICE detector. The measurements of the jet momentum fraction carried by the D meson in pp collisions at $\sqrt{s}=5.02$ TeV and $13\ \mathrm{TeV}$ will be presented. The comparison to POWHEG+PYTHIA will be shown. Moreover, the first measurement at the LHC of the jet-momentum fraction carried by the $\mathrm{Λ_c^+}$ baryon in pp collisions at $\sqrt{s}=13\ \mathrm{TeV}$ will be reported. Production of heavy-flavour jets in pp collisions at $\sqrt{s}=5.02\ \mathrm{TeV}$ will be also addressed with charged jets tagged by heavy-flavour hadron decay electrons and beauty-hadron decay vertices. The nuclear modification factor of heavy-flavour tagged jets in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02\ \mathrm{TeV}$ will be presented.
