Description
In the early stages of heavy-ion collisions, the hot QCD matter expands more longitudinally than transversely.
This imbalance causes the system to become rapidly colder in the longitudinal direction and a local momentum anisotropy appears.
In this talk we study the heavy-quarkonium spectrum in the presence of a small plasma anisotropy.
We work in the framework of potential non-relativistic QCD at finite temperature.
We inspect arrangements of non-relativistic and thermal scales complementary to those considered in the literature.
In particular, we consider temperatures larger and Debye masses smaller than the binding energy,
which is a temperature range relevant for presently running LHC experiments.
In this setting we compute the leading thermal corrections to the binding energy and the thermal width induced by quarkonium gluo-dissociation
