14. Heavy flavor transport and exotic hadron production in heavy ion collisions

For heavy ion collisions in the TeV beam energy region, the large number of initial hard scatterings create a richly “doped” hot quark-gluon plasma embedding an unparalleled abundance of charm quarks/anti-quarks. This provides a uniquely “charming” environment for the massive production of exotic hadrons in nuclear collisions and possibly helps solve puzzles about their intrinsic structures,...

We investigate the in-medium kinetics of heavy quarkonia focusing on recent developments and results for the $\psi(2S)$, X(3872), and $B_c$ particles in ultra-relativistic heavy-ion collisions (URHICs). Based on our previous calculations, our approach is governed by two transport parameters for each quarkonium state: the equilibrium limit and inelastic reaction rate. The equilibrium limits are...

21. Exotic charmed hadrons production in relativistic heavy-ion collisions

The deconfined quark-gluon plasma (QGP) created in relativistic heavy-ion collisions is not only a perfect fluid with very small $\eta/s$ but also a most "charming" system with hundreds of charm quarks. Meanwhile, it is widely accepted that the quark hadronization mechanism changes with the appearance of QGP. The production of charmed hadrons differs significantly in $A$-$A$ collisions from...

Using the coalescence model, we calculate the multiplicities of X(3872) and $T_{cc}^+$ at the end of the quark gluon plasma phase in nucleus-nucleus collisions at the LHC. Then, using effective lagrangians and a rate equation, we calculate the changes in these multiplicities during the hadron gas phase. Finally, we present the multiplicities at the end of the collisions and also plot them as a...
