论文摘要
我们研究$ b_c $在有限温度下以解离和再生的运输方法中的高能核碰撞产量。由于P+P碰撞的罕见产量以及Quark-Gluon等离子体中不相关的$ C $和$ \ b $ Quarks的强大组合,因此在大型Hadron Collider的核冲突中,$ B_C $的产量大大提高。此外,$ b_c $的中心性和动量依赖性产量敏感地反映了底部夸克的热化度。新观察到的实验数据偏离了夸克 - 杜松等离子体中的热底夸克分布很远。
We study $B_c$ production in high-energy nuclear collisions in a transport approach with dissociation and regeneration at finite temperatures. Due to the rare production in p+p collisions and the strong combination of uncorrelated $c$ and $\bar b$ quarks in the quark-gluon plasma, the $B_c$ yield is significantly enhanced in the nuclear collisions at the Large Hadron Collider. Moreover, the centrality and momentum-dependent yield of $B_c$ sensitively reflect the thermalization degree of bottom quarks. And the newly observed experimental data favors a far from the thermal bottom quark distribution in the quark-gluon plasma.
