Abstract

Three HERMES measurements of hard-exclusive processes usefull for testing Generalized Parton Distributions (GPDs) are described. Firstly, Spin Density Matrix Elements (SDMEs) are determined from exclusive diffractive ρ0 and ϕ electroproduction in the HERMES experiment at 27.5 GeV beam energy. Then, Transverse Target Spin Asymmetry (TTSA) in exclusive ρ0 production and in Deeply Virtual Compton Scattering (DVCS) process on a transversally polarized hydrogen target is determined.
