Overview of the Muon Proton Scattering Experiment, MUSE

The proton radius puzzle became prominent in 2010 when the muonic spectroscopy result from the CREMA collaboration found that the charge radius was at least five standard deviations smaller than the previously accepted value. In the past eleven years, a myriad of experiments have utilized different methods to gather information and learn more about the structure of the proton and its charge radius. The MUon-proton Scattering Experiment - MUSE - at Paul Scherrer Institut (PSI) in Villigen, Switzerland, aims to reassess the proton charge radius and the discrepancies that remain by performing the first simultaneous measurement of elastic electron and muon scattering off the proton with the PiM1 beamline at PSI. In addition, MUSE will be able to directly measure two-photon exchange effects by measuring both charge states. This talk will give an overview of MUSE, including the physics motivations, experimental hardware configuration and capabilities, as well as the current status of the collaboration.
