Abstract

There are two important different mechanisms, the imaginary potential and entropic force, to investigate the dissociation of heavy quarkonia. In this paper, we calculate these two quantities for static and moving quarkonia in the rotating black 3-brane Type IIB supergravity solution dual to N = 4 super Yang–Mills theory on the Coulomb branch (cSYM) at strong coupling. At T = 0, there are two black hole branches: the large and small black hole branches. We investigate the effects of rotating parameter and rapidity for the static and moving quakonium at the large and small black hole branches. We find both mechanisms have the same results. In the large black hole branch: as T/ and β increase the thermal width decreases and so the suppression becomes stronger. In the small black hole branch: increasing T/ leads to increasing the thermal width and the quarkonium dissociates harder but β has an opposite effect
