Description
Abstract: The MUon Scattering Experiment (MUSE) at PSI is part of a suite of experiments that aim to assess the proton radius puzzle that surfaced in 2010, when a high precision measurement of the proton charge radius reported a value that was five standard deviations smaller than the value accepted at the time. The MUSE experiment aims to address the puzzle by simultaneously measuring elastic electron-proton and muon-proton scattering from a liquid hydrogen target. MUSE uses leptons in positive and negative charge states, which enables it to test lepton universality and directly measure two-photon exchange, in addition to its principal objective of extracting form factors and proton radii. Achieving the precision necessary to inform the puzzle requires extensive understanding of the performance of all detector systems in the experiment. In this talk, I will present an overview of MUSE, and discuss its current status and plans.
