Hard Exclusive Processes at COMPASS and COMPASS-II / D'Hose, N (Saclay) /for the COMPASS collaboration
A major part of the future COMPASS program [1] is dedicated to the study of Deeply Virtual Compton Scattering (DVCS) and Meson Production (DVMP) to investigate nucleon structure through Generalised Parton Distributions (GPD). The high energy of the muon beam allows us to measure the xB-dependence of the t-slope of the pure DVCS cross section and to study nucleon tomography. [...]

Feasibility study of Deeply Virtual Compton Scattering using COMPASS at CERN / D'Hose, N (Saclay) ; Burtin, E (Saclay) ; Guichon, P A M (Saclay) ; Marroncle, J (Saclay)
This paper presents the reactions which can be performed at COMPASS to study the Generalized Parton Distributions (GPDs). The high energy muon beam at CERN allows to measure Hard Exclusive Meson Production or Deeply Virtual Compton Scattering (DVCS) in the Bjorken regime in a large range of $Q^{2}$ and $x_{Bj}$ (1.5 $ \leq Q^{2} \leq$ 7.5 GeV$^{2}$ and 0.03 $\leq x_{Bj}\leq$ 0.25).

The $t$-dependence of the pure DVCS cross section at COMPASS / Joerg, Philipp (Freiburg U.) /COMPASS Collaboration
The key reactions to study the Generalised Parton Distributions are Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP). At COMPASS, these processes are investigated using a high intensity muon beam with a momentum of 160\,GeV/c and a 2.5\,m-long liquid hydrogen target. [...]
