Feasibility study of deeply virtual Compton scattering using COMPASS

Deeply virtual Compton scattering is a very suitable tool to learn about generalized parton distributions. We propose to use the 190 GeV (or 100 GeV) muon beam at CERN to study DVCS in the Bjorken regime. The high energy of the lepton beam and the present luminosity allows to measure the absolute cr...

Sumario:Deeply virtual Compton scattering is a very suitable tool to learn about generalized parton distributions. We propose to use the 190 GeV (or 100 GeV) muon beam at CERN to study DVCS in the Bjorken regime. The high energy of the lepton beam and the present luminosity allows to measure the absolute cross section or beam charge asymmetry in a large range of Q/sup 2/ and x/sub Bj/ (1<or=Q/sup 2/<or=7 GeV/sup 2/ and 0.03<or=x/sub Bj/<or=0.27). We discuss the experimental implications for the existing COMPASS set-up. (4 refs).
