Abstract
In this paper we study azimuthal asymmetries of the muon pair production in ultraperipheral heavy-ion collisions within the joint impact parameter and transverse momentum-dependent framework. The final state QED radiation effects are resummed to all orders in perturbation theory, where the complete muon mass corrections are also taken into account. We further make numerical estimations for azimuthal asymmetries in the different kinematic regions accessible at RHIC and LHC with the derived resummation formula. We find that the lepton mass effects can give sizable corrections to the asymmetries at relatively large pair transverse momentum at RHIC energy.
