Future Measurement of the Proton Radius at COMPASS — •Sebastian Uhl for the COMPASS collaboration — Physik Department, Technische Universität München, Garching

The observed difference of the proton charge radius measured on the one hand in electron scattering experiments and in hydrogen spectroscopy and on the other hand in the spectroscopy of muonic hydrogen has triggered many efforts to clarify its origin. An elastic-scattering experiment using a high-energetic muon beam could provide a different view at this issue. Compared to electron scattering, such an experiment will be affected much less by radiative corrections.

We will present ideas, how such a measurement can be performed in the framework of a future COMPASS program.
