Abstract
En 中文
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.
