Title: On the Run from the Dark Side of the Muon

Abstract: In a high-energy muon collider, the beam emits collinear particles that act as partons within the muon with parton distribution functions. I will present a method to search for new physics by exploiting deviations in Standard Model parton distribution functions due to modifying their scale evolution. One can simply select an ensemble of final states that are produced in various hard processes and measure the distribution of their invariant mass. For a benchmark Z’ model, I will show that this scheme outperforms directly producing the new physics in a mass range between 50 GeV and 110 GeV. This result is limited by our lack of a finalized detector design, but a real experiment can systematically improve on this strategy by analyzing more final states and kinematic variables.
