MUSE: Measuring the proton radius with muon-proton scattering — •Jan Christopher Bernauer — Massachusetts Institute of Technology, Cambridge, USA

The proton radius has been measured so far using electron-proton scattering, electronic Hydrogen spectroscopy and muonic Hydrogen spectroscopy, the latter producing a much more accurate, but seven sigma different, result, leading to the now famous proton radius puzzle. The MUSE collaboration aims to complete the set of measurements by using muon scattering to determine the proton radius and to shed light on possible explanations of the discrepancy. The talk will give an overview of the experiment motivation and design and a status report on the progress.
