论文摘要
In this paper we have shown theoretical model comparisons with ALICE results for average D mesons (D$^0$, D$^+$, D$^{*+}$ and $D^+_s$) in $p$+Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV for various centralities.根据碰撞中心性（$ \ displayStyle {q_ {q_ {ppb}} $）的$ p_t $依赖性核修饰因子的AMPT计算和重型Quark PQCD模型，NLO（MNR）的计算已用于研究$ p_t $依赖的核修饰因子。发现NLO模型具有其参数化的$ \ displayStyle {k_t} $扩展方案，其结果与Alice的$ P $+PB碰撞的已发布的D-Meson数据非常匹配。同样，AMPT运输计算显示结果的中心性依赖性很强，但低估了实验数据。两种模型与实验数据的差异已被讨论。
In this paper we have shown theoretical model comparisons with ALICE results for average D mesons (D$^0$, D$^+$, D$^{*+}$ and $D^+_s$) in $p$+Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV for various centralities. Transport calculations of AMPT and calculations from heavy quark pQCD model, NLO(MNR) have been used for the study of $p_T$ dependent nuclear modification factors in terms of collision centrality ($\displaystyle{Q_{pPb}}$) and the central-to-peripheral ratios ($\displaystyle{Q_{cp}}$) of D mesons. It is found that NLO model with its parametrized $\displaystyle{k_T}$ broadening scheme produces results those closely match with the published D-meson data of $p$+Pb collisions from ALICE. Likewise AMPT transport calculation shows a strong centrality dependence in results but underestimates the experimental data. The differences of both models with experimental data have been discussed.
