Dark Photon Production Via Inelastic Proton Bremsstrahlung with Pauli Form Factor

Year: 2025

Type: article

Abstract: We study the production of vector portal mediators, dark photons, with masses in the range 0.4–1.8 GeV in proton-proton collisions via the process of inelastic proton bremsstrahlung. In contrast to previous studies, we take into account the contribution of Pauli electromagnetic form factor to differential cross section and introduce two new splitting functions of the proton. We show that their contributions can become leading in the mass region 0.9–1.8 GeV and present the updated estimate for the sensitivity of the future SHiP experiment to visible decays of dark photons.
