Abstract / Bemerkung
We present a study of charmonia in hot gluonic plasma, for temperatures up to three times the deconfinement transition temperature T-c. q (q) over bar systems with quark masses close to the charm mass and different spin-parity quantum numbers were studied on very fine isotropic lattices. The analysis of temporal correlators, and spectral functions constructed from them, shows that the J/psi and eta(c) survive up to quite high temperatures, with little observable change up to 1.5T(c), and then gradually weaken and disappear by 3T(c). For the scalar and axial vector channels, serious modifications are induced by the hot medium already close to T-c, possibly dissociating the mesons by 1.1T(c).
