Abstract
A major part of the future COMPASS program is dedicated to investigation of the nucleon structure by studying Generalised Parton Distributions (GPDs) through Deeply Virtual Compton Scattering (DVCS) andMeson Production (DVMP). Already new results of the transverse target spin azimuthal asymmetry Asin(φ−φs) UT for hard exclusive ρ0-meson production on a transversely polarized target have been obtained. Now the realisation of the first DVCS test run with a 2.5m long liquid hydrogen target surrounded by a new ToF system and an extended calorimetry has been achieved. The availability of muon beams with high energy and opposite charge and polarization will allow to access the Compton form factor related to the dominant GPD H and to measure the xB-dependence of the t-slope of the pure DVCS cross section to study nucleon tomography. In the future we consider to use a transversely polarized proton target to constrain the GPD E.
