Description
Heavy quarkonium is one of the probes of the formation of a quark-gluon
plasma in heavy-ion collisions. Recently, it has been found that its
interaction with the medium can be described, in the intermediate
temperature regime, by a rate equation for the singlet to octet
transition combined with a Langevin equation for the octet to octet
transition. Such a description can be justified from first principles
using the open quantum system formalism and it can be shown that it
leads to the correct thermalization of the system. In this talk, I will
present an application of this model to the prediction of the
suppression pattern of Upsilon(1S) at LHC and I will discuss how
non-perturbative input from the lattice computation of the real part of
the potential can be introduced in the model. The results that are
found, using just a simple Bjorken evolution, are in qualitative
agreement with experimental observations.
