Abstract
We investigate proton-antiproton (\(p\overline{p}\)) pair production via photon-photon fusion in the ultra-peripheral collisions at the relativistic heavy ion collider (RHIC), employing a joint impact parameter and transverse momentum dependent formalism. We consider proton exchange, s-channel resonance, and hand-bag mechanisms, predicting differential distributions of \(p\overline{p}\) production. Our theoretical predictions can be tested against future measurements at RHIC to enhance our understanding of photon-photon interactions in strong electromagnetic fields.
