Analysis of COMPASS data on DVCS — •Johannes Giarra — on behalf of the COMPASS collaboration - Institut für Kernphysik, Johannes Gutenberg-Universität Mainz, Johann-Joachim-Becher-Weg 45, 55099 Mainz

In 2016 and 2017 a measurement of the exclusive single photon production was performed at the M2 beamline of the CERN SPS, scattering a 160 GeV positive and negative charged muon beam off a liquid hydrogen target. During the measurement all particles participating in the process were measured. To perform an exclusive measurement the COMPASS spectrometer was supplemented by an additional electromagnetic calorimeter to increase the acceptance for the detection of large angle photons. The recoiling protons were measured by a time of flight (TOF) detector surrounding the target.
The talk will summarize the current status of the analysis to determine the cross section of the Deeply Virtual Compton Scattering (DVCS). Thereby the focus will be on determining the Bethe-Heitler contribution to the cross section as well as the method to determine and remove the π0 contamination from the exclusive single photon sample.
