Description

Abstract:

In ultraperipheral Pb+Pb collisions, intense electromagnetic fields may enable the generation of magnetic monopole pairs via the Schwinger mechanism. Due to their high ionization and unique trajectories in a solenoidal magnetic field, monopoles are expected to leave numerous clusters in the innermost ATLAS pixel detector without associated reconstructed charged-particle tracks or calorimeter activity. I will present a search for monopole-pair production in ultraperipheral Pb+Pb collisions in the monopole mass range of 20-150 GeV, based on 5.36 TeV data recorded in 2023 by the ATLAS experiment at the Large Hadron Collider. Semiclassical free particle approximation model and a recent search limits obtained by the MoEDAL Collaboration are compared with the ATLAS results.

Important: This seminar is held in building D-11 room 104.
