Description
In heavy ion collisions, quarkonium is produced in a rapidly thermalized deconfined medium. Quarkonium production can be understood in terms of Langevin dynamics of heavy quarks interacting through medium modified potential [1]. This framework was used sucessfully to understand charmonium production at RHIC [1,2] including recombinant production [2] when realistic values of the heavy quark diffusion constant are used together
with a lattice QCD inspired potential. It also explains the J/psi production at LHC including its centrality independence [3].
We extend this framework to upsilon production by including the thermal dissociation of formed bottomonia. This is done with a transport (local
rate) equation followed by Langevin dynamics of the correlated $Q\bar{Q}$ states. The bulk evolution of the medium is treated using MUSIC, a 3+1-dimensional hydrodynamical simulator of heavy ion collisions, while we make use of the latest lattice results on the $Q\bar{Q}$ potential. We make
prediction for the bottomonium production at full LHC energy.
