论文摘要
在这一贡献中，pb-pb collisions in $ \ sqrt {s _ {\ scriptScriptScriptScriptStystyle \ rm nn} $ 5.02 primants的核修饰因子（$ r _ {\ rm aa} $）的中心性依赖性的最终测量值的最终度量测量值。这些测量值对美容夸克的能量损失和强国化的中等质量质量构成了重要的限制。 $ p _ {\ rm t} $ - 集成的非预订$ \ rm d^0 $ $ r _ {\ rm aa} $将首次提出，并将与提示$ \ rm d^0 $一个。这种比较将阐明魅力和美容夸克之间可能的不同阴影效果。此外，将讨论中央和半中央PB-pb碰撞$ \ sqrt {s _ {\ scriptScriptScriptStystyle \ rm nn}} $ = 5.02 TEV的第一个测量。非预付款$ \ rm d_s $测量值提供了有关$ \ rm b_s $梅森族的生产和强调的其他信息。最后，在$ \ sqrt {s _ {\ scriptScriptStystyle \ rm nn}} $ = 5.02 tev的$ \ sqrt {s _ {s _ {s _ {s _ {s _ {s _ {s _ {s _ sqrt {s _ collisions中的非累积d-mesons流量的第一个测量。这种测量可以限制在热和密集的QCD培养基中美容夸克的热量程度。
In this contribution, the final measurements of the centrality dependence of the nuclear modification factor ($R_{\rm AA}$) of non-prompt $\rm D^0$ in Pb--Pb collisions at $\sqrt{s_{\scriptscriptstyle \rm NN}}$ = 5.02 TeV will be presented. These measurements provide important constraints to the in-medium mass dependent of energy loss and hadronisation of the beauty quark. The $p_{\rm T}$-integrated non-prompt $\rm D^0$ $R_{\rm AA}$ will be presented for the first time and will be compared to the prompt $\rm D^0$ one. This comparison will shed light on possible different shadowing effects between charm and beauty quarks. In addition, the first measurements of non-prompt $\rm D_s$ production in central and semi-central Pb--Pb collisions at $\sqrt{s_{\scriptscriptstyle \rm NN}}$ = 5.02 TeV will be discussed. The non-prompt $\rm D_s$ measurements provide additional information on the production and hadronisation of $\rm B_s$ mesons. Finally, the first measurement of non-prompt D-mesons elliptic flow in Pb--Pb collisions at $\sqrt{s_{\scriptscriptstyle \rm NN}}$ = 5.02 TeV will also be discussed. This measurement can constrain the degree of thermalisation of beauty quarks in the hot and dense QCD medium.
