Heavy quarkonium's relative motion in the quark-gluon plasma can be evolved with a Lindblad master equation whose stochastic unraveling includes drag, and in one-dimensional simulations the pair thermalizes with a temperature close to the medium's.

abstract
We compute the QGP suppression of Upsilon(1s), Upsilon(2s), Upsilon(3s), chi_b1, and chi_b2 states in sqrt(s_NN)=2.76 TeV Pb-Pb collisions. Using the suppression of each of these states, we estimate the inclusive R_AA for the Upsilon(1s) and Upsilon(2s) states as a function of N_part, y, and p_T including the effect of excited state feed down. We find that our model provides a reasonable description of preliminary CMS results for the N_part-, y-, and p_T-dependence of R_AA for both the Upsilon(1s) and Upsilon(2s). Comparing to our previous model predictions, we find a flatter rapidity dependence, thereby reducing some of the tension between our model and ALICE forward-rapidity results for Upsilon(1s) suppression.

Quantum Brownian motion of a heavy quark pair in the quark-gluon plasma
Heavy quarkonium's relative motion in the quark-gluon plasma can be evolved with a Lindblad master equation whose stochastic unraveling includes drag, and in one-dimensional simulations the pair thermalizes with a temperature close to the medium's.
