Description
High-Electric-Charge Objects (HECOs) are featured in numerous theoretical particle physics models extending beyond the Standard Model.
HECOs are actively pursued in contemporary collider experiments like the LHC. In these searches, the determination of mass limits for HECOs has relied on Drell-Yan and Photon-Fusion processes at the tree level thus far. However, these approximations lack reliability due to the breakdown of perturbative QED calculations caused by the large electric charge of HECOs. To address this issue, we introduce a Dyson-Schwinger resummation scheme, enabling computations of HECO-production cross sections. Consequently, we achieve more accurate mass constraints from ATLAS and MoEDAL investigations.
