Abstract

We compute bottomonium suppression and elliptic flow within the potential nonrelativistic quantum chromodynamics effective field theory using an open quantum systems approach. For the hydrodynamical background, we use 2+1D MUSIC second-order viscous hydrodynamics with IP-glasma initial conditions and evolve bottom/antibottom quantum wave packets in real time in these backgrounds. We find that the impact of fluctuating initial conditions is small when compared to results obtained using smooth initial conditions. Including the effect of fluctuating initial conditions, we find that the Υ(1S) integrated elliptic flow is v2[1S]=0.005±0.002±0.001, with the first and second variations corresponding to statistical and systematic theoretical uncertainties, respectively.
