Dynamical evolution of heavy quarkonia in a deconfined medium

Borghini N, Gombeaud C. Dynamical evolution of heavy quarkonia in a deconfined medium.; 2011.We investigate some consequences of the possibility that heavy quarkonia in aquark-gluon plasma possess different (quasi-) bound states, between whichtransitions are possible. In particular, we show that the time-evolutioneigenstates in the medium are mixtures of the vacuum eigenstates. This leads toabundance ratios of quarkonia that differ from those predicted in statisticalmodels or in the sequential-melting picture
