ALICE质子-质子碰撞中D介子的产生

D-meson production in proton-proton collisions with ALICE at the LHC

Julien Hamon

摘要:

本文综述了ALICE最近在$\sqrt{s}~=~2.76$、5、7、8和13 TeV质子-质子碰撞中进行的$\mathrm D^{0}$、$\mathrm D^{+}$和$\mathrm D^{*+}$测量。最小偏差生产截面,以及它们的能量和物种的依赖性,相比微扰QCD计算。与唯象模型相比,D介子产额与事件多重性的演变。

英文摘要:

In this paper, an overview of recent $\mathrm D^{0}$, $\mathrm D^{+}$ and $\mathrm D^{*+}$ measurements, performed by ALICE in proton--proton collisions at $\sqrt{s}~=~2.76$, 5, 7, 8 and 13 TeV, is reported. The minimum-bias production cross sections, as well as their energy and species dependences, are compared to perturbative QCD calculations. The evolution of the D-meson yields with the event multiplicity is compared to phenomenological models.
