Measurement of the electromagnetic form factors of the proton in the Q2 range 0.5 to 2 GeV2/c2 — •Julian Müller for the A1 collaboration — Institut für Kernphysik, Mainz
In spring 2015 a new measurement of the form factors of the proton was performed at the MAMI accelerator in Mainz. The form factors will be determined via elastic electron proton scattering, measured with the three spectrometer facility of A1. Now, that the higher beam energies provided by a third stage of the accelerator are available, we were able to increase the limit in Q2 from 0.5 up to 2 GeV2/c2. Therefore, the main focus of this experiment will be the precise determination of the magnetic form factor of the proton. This talk will cover the experimental setup and the current status of the analysis. Together with previous experiments at A1 at lower values of Q2, we aim to contribute to the solution of the proton radius puzzle.
