Exclusive heavy quark-pair production in ultraperipheral collisions
In this article, we study the fully differential observables of the exclusive production of heavy (charm and bottom) quark pairs in high-energy ultraperipheral pA and AA collisions. In these processes, the nucleus A serves as an efficient source of the photon flux, while the QCD interaction of the produced heavy-quark pair with the target (p or A) proceeds via an exchange of gluons in a color sing
