Abstract

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 Q² and x_Bj (1.5<Q²<7.5 GeV² and 0.03<x_Bj<0.25). Exploratory measurements dedicated to rho₀ or pi₀ production can be investigated with the present setup. DVCS measurement require an upgrade of the COMPASS setup.
