abstract

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.

  1. Nuclear modification of $B_c$ mesons in relativistic heavy-ion collisions based on a linear Boltzmann transport model

    hep-ph 2025-02 conditional novelty 5.0 of 10

    A linear Boltzmann transport model with Yukawa and string interactions reproduces the measured B_c nuclear modification in Pb+Pb collisions and predicts larger low-pT B_c R_AA in Au+Au at RHIC than at the LHC.
