Dissociation of heavy quarkonia at finite μ (2209.07132v4)

Abstract: We studied the properties of the heavy quarkonia in the presence of finite quark-chemical potential for different number of flavors by using the quasi particle approach. The effect of the finite quark-chemical potential has been incorporated through the quasi-particle Debye mass to examine the binding energies of the quarkonium states. From the imaginary part of the potential we have calculated the thermal width of the ground state of the quarkonia and found that the thermal width increases with finite quark-chemical potential. The dissociation temperature (T_D) of the J/psi and Upsilon have been calculated in the presence of finite quark-chemical potential for different flavors (i.e., N_f = 1, 2 and 3). The effect of the finite quark-chemical potential on the mass spectra of the quarkonium states has been also studied.
