论文摘要
魅力 - hadron具有多功能的辐射化学，其特征是它们的不同物种之间的各种横向摩托依赖性比率。特别是，魅力式辐射化学可以在相同的质子 - 蛋白质碰撞中对相同能量的质子 - 普罗顿碰撞进行修改，这是由于新的Quark-gluon Plasma（QGP）环境中的新型扩散和夸张夸克机制引起的。受到PB-PB和Au-Au碰撞中魅力 - 饰面腐烂（与底部衰减相距）的卵巢的最新测量的启发，我们研究了魅力辐射化学对Leptonic观测值的影响。 We find that full consideration of charm hadro-chemistry in both proton-proton and heavy-ion collisions causes only mild change of charm-leptons' suppression factor with respect to previous calculations hadronizing charm quarks into $D$ mesons only, whereas the resulting change (increase) in the charm-leptons' elliptic flow turns out to be more pronounced as a consequence of the larger collectivity of $Λ_c$ baryons than $ d $介子。
Charm-hadrons possess versatile hadro-chemistry as characterized by various transverse-momentum-dependent ratios between their different species. In particular, the charm hadro-chemistry may be modified in relativistic heavy-ion collisions with respect to proton-proton collisions at the same energy, as caused by novel diffusion and hadronization mechanisms of charm quarks in the environment of the created quark-gluon plasma (QGP) in the former. Inspired by recent measurements of leptons from charm-hadron decays (separated from bottom decays) in Pb-Pb and Au-Au collisions, we investigate the effects of the charm hadro-chemistry on the leptonic observables. We find that full consideration of charm hadro-chemistry in both proton-proton and heavy-ion collisions causes only mild change of charm-leptons' suppression factor with respect to previous calculations hadronizing charm quarks into $D$ mesons only, whereas the resulting change (increase) in the charm-leptons' elliptic flow turns out to be more pronounced as a consequence of the larger collectivity of $Λ_c$ baryons than $D$ mesons.
