Date/Time: Thu Jan 08 2026 at 14:00<br/><br/>Location: Auditorium/Remote<br/><br/>Speaker: Ethan Cline (MIT)<br/><br/>Title: Understanding the Proton with MUSE<br/><br/>Abstract: The MUon Scattering Experiment (MUSE), which takes place in the Paul Scherrer Institute (PSI) at the PiM1 beamline, aims to simultaneously perform elastic ep and µp scattering in order to determine the proton charge radius. MUSE was originally motivated by the proton charge radius puzzle. However with the beamline and kinematics available to the experiment, MUSE has a broad physics reach. As the experiment has access to both positively and negatively charged leptons, a precise two photon exchange measurement can be performed for both electrons and muons in the 0.002 < Q2 < 0.08 GeV2 and 0.26 < e < 0.94 regime. The experiment has both a liquid hydrogen target and a carbon target, allowing for a variety of precise cross section measurements. Additionally with access to p± in the beam it is also possible to measure absolute and relative pion-proton scattering cross sections to high precision with the MUSE detector. In this talk we will discuss the physics reach and the current status of MUSE and the projected uncertainties for the measurements that will be made.
