title = "Bethe-Salpeter amplitudes of Upsilons",
abstract = "Based on lattice nonrelativistic QCD (NRQCD) studies, we present results for Bethe-Salpeter amplitudes for ϒ(1S), ϒ(2S), and ϒ(3S) in vacuum as well as in quark-gluon plasma. Our study is based on 2+1 flavor 483×12 lattices generated using the Highly Improved Staggered Quark action and with a pion mass of 161 MeV. At zero temperature, the Bethe-Salpeter amplitudes follow the expectations based on nonrelativistic potential models. At nonzero temperatures, the interpretation of Bethe-Salpeter amplitudes turns out to be more nuanced but consistent with our previous lattice QCD study of excited Upsilons in quark-gluon plasma.",
