Abstract:
Magnetic monopoles are hypothetical particles that carry isolated magnetic charge – a single north or south pole. Dirac showed that their existence would explain the quantization of the electric charge. Monopoles are predicted by all grand unification theories that incorporate electromagnetism. In recent years, monopoles with masses as low as a few TeV were also discovered in various BSM theories based on spontaneous broken gauge symmetries, renewing the motivation to search for their direct production at colliders. This talk will describe the motivation, recent results, and future prospects of an ongoing experimental program to discover these elusive particles. It will highlight, in particular, the recent pioneering search for production of magnetic monopoles in heavy-ion collisions via the Schwinger mechanism that overcome limitations of previous searches and established first reliable mass limits on monopoles with charges of up to 3 units of Dirac charge. The most recent result, which extended the reach to unprecedentedly high magnetic charges, will also be introduced. The talk will conclude by contemplating the future of monopole searches at hadron colliders and in cosmic rays.
About the speaker:
Dr. Igor Ostrovskiy worked at JINR and INFN before receiving his Ph.D. at the University of Alabama, where he performed the first analysis of the Double Chooz far detector data that provided a hint of non-zero value of the neutrino mixing angle θ13. He then did a postdoc at Stanford before returning to the University of Alabama where he currently holds an associate professor position. His group's two primary research foci are searches for magnetic monopoles at the LHC and R&D for the next generation of liquid-xenon detectors that will search for dark mater and neutrinoless double beta decay. He is a member of the MoEDAL, DARWIN, EXO, and MONUMENT collaborations.
