Description
We discuss charm-strange mesons, Ds, Ds, Ds0(2317), Ds1(2460), and X(3915) mesons produced from charm and strange quarks in the quark-gluon plasma in heavy-ion collisions at \sqrt{s_{NN}}=5.02 TeV. We first investigate the transverse momentum distribution of charm and strange quarks at \sqrt{s_{NN}}=5.02 TeV in the quark-gluon plasma based on transverse momentum distributions of \phi and D^0 mesons. Then, we calculate the yields and transverse momentum distributions of Ds, Ds, Ds0(2317), Ds1(2460), and X(3915) mesons. We demonstrate that our results agree well with experimental measurements for the Ds meson and argue that the strangeness enhancement has a significant impact on the production of charm-strange mesons in heavy-ion collisions. We also present, in particular, the transverse momentum distributions and yields of Ds0*(2317) and X(3915) mesons for their various possible states, and show how their yields and transverse momentum distributions depend on their internal structures.
