Analysis of 2016 COMPASS data on DVCS — •Johannes Giarra — for the COMPASS Collaboration, Institut für Kernphysik, Mainz, Germany
The COMPASS Experiment is a fixed target experiment at the M2 beamline at CERN. In 2016 deeply virtual compton scattering (DVCS) was measured by scattering a polarized positive and negative charged muon beam off a liquid hydrogen target. From these measurements the charge and spin cross section difference can be determined. This difference is related to a generalized parton distribution function, which allows to study the three dimensional structure of the proton. The talk will discuss the status of the ongoing analysis with a focus on determination of the luminosity and comparison of the data taken with the positive and negative charged muon beam.
