Hunting wino and higgsino dark matter at the muon collider

by Federico Meloni

US/Eastern
Description

Events containing disappearing tracks originating from the decay of a heavy and electrically charged long-lived particle to a pair of undetectable particles are key to the discovery of compelling minimal dark matter models at collider experiments. This talk will present the prospects for a search for such experimental signature at a future muon collider. Techniques dedicated to the suppression of the backgrounds induced by the in-flight decays of the muon beams will be presented and the results compared to other future collider experiments in the context of MSSM higgsino and wino dark matter. In particular, this talk will show how a muon collider operating at a centre of mass energy of 10 TeV can rival, and in same cases outperform, the sensitivity of a 100 TeV proton proton collider.
