Abstract:

Charmonia, bound states of charm and anticharm quarks, are not only rich laboratories of strong interaction in vacuum，but also constitute versatile probes of the Quark-Gluon Plasma (QGP) as created inrelativistic heavy-ion collisions. In this talk, we are going to present a computation of charmonia dissociation cross section by thermal quarks and gluons at the next-to-leading order and then its application to charmonia semiclassical transport in the QGP, highlighting the regeneration production of J/psi and its excited state psi(2S).
