We deploy a kinetic-rate equation to evaluate the transport ofJ/ψ, ψ(2S),BcandX(3872) in ultrarelativistic heavy-ion collisions and compare their production yields to experimental data from the Large Hadron Collider. The rate equation has two main transport parameters: the equilibrium limit and reaction rate for each state. The temperature-dependent equilibrium limits include charm- and bottom-quark fugacities based on their initial production. The reaction rates for charmonia, bottomonia andBcrely on charm- and bottomquark masses and binding energies from a thermodynamicT-matrix approach. For theX(3872) particle, internal structure information is encoded in reaction rates and initial conditions in the hadronic phase via two different scenarios: a loosely bound hadronic molecule vs. a compact tetraquark.
