## T-matrix approach to quarkonium correlation functions in the quark-gluon plasma

We study the evolution of heavy quarkonium states with temperature in a quark-gluon plasma (QGP) by evaluating the in-medium Q-Q T-matrix within a reduced Bethe-Salpeter equation in both S- and P-wave channels. The underlying interaction kernel is extracted from recent finite-temperature QCD lattice calculations of the singlet free energy of a Q-Q pair. The bound states are found to gradually move above the Q-Q threshold after which they rapidly dissolve in the hot system. The T-matrix approach is particularly suited to investigate these mechanisms as it provides a unified treatment of bound and scattering states including threshold effects and themore »
