摘要:

本文报道了LHC能区pp、p-Pb、Pb-Pb和Pb-Pb碰撞中初级带电粒子和中性介子产生的ALICE结果。本文讨论了在宽$p_{\rm T}$范围和不同中心度类下,Pb-Pb、Pb-Pb和p-Pb碰撞中初级带电粒子和轻中性介子的核修正因子$R_{\rm AA}$的测量。我们比较了不同碰撞系统的核修正因子作为横动量,碰撞中心以及带电粒子多重性(${\rm d}N_{\rm ch} / {\rm d}η$)的函数。我们还提出了模型计算的实验结果的比较。

英文摘要:

We report recent ALICE results on primary charged particle and neutral meson production in pp, p--Pb, Pb--Pb and Xe--Xe collisions at LHC energies. In this article, measurements of the nuclear modification factors $R_{\rm AA}$ of primary charged particles and of light neutral mesons in Pb--Pb, in Xe--Xe and in p--Pb collisions in a wide $p_{\rm T}$ range and different centrality classes are discussed. We compare the nuclear modification factors obtained for different collision systems as a function of transverse momentum, collision centrality as well as charged particle multiplicity (${\rm d}N_{\rm ch} / {\rm d}η$). We also present comparison of experimental results to model calculations.
