摘要：
We employ the transport model coupled with hydrodynamic equations to study the charmonium dissociation and regeneration in the quark-gluon plasma (QGP) with the large baryon chemical potential in Au-Au collisions at the energies of root sNN = 39, 14.5, and 7.7 GeV. The baryon chemical potential mu B is encoded in both Debye mass characterizing the heavy-quark potential and also the equation of state of the bulk medium. After considering mu B corrections in both heavy quarkonium and the QGP medium, we calculate the nuclear modification factor RAA of charmonium. We find the mu B influence on charmonium production at root sNN = 39 and 14.5 GeV is negligible, while the RAA of charmonium is reduced considering mu B influence at root sNN = 7.7 GeV Au-Au collisions, which is crucial for studying charmonium production in low energy and also fixed-target heavy-ion collisions.
