Path Length Reconstruction for MUSE

The Muon Scattering Experiment (MUSE) at the Paul Scherrer Institute aims to measure the elastic scattering of muons and electrons from a liquid hydrogen target. MUSE was motivated by the proton radius puzzle, and the experiment is the first high precision muon scattering radius measurement. MUSE measures with both positively and negatively charged leptons, including muons, electrons, and pions. With the mixed lepton beam, it is important to identify and reconstruct events of different types, with the ultimate goal of having clearly defined scattering events of different types. This presentation will discuss the method and process for reconstruction of incoming and scattered particle paths for MUSE in the effort to identify reactions and extract form factors and radii.
