Abstract
The transverse target spin azimuthal asymmetry AUTsin(ϕ−ϕS) in hard exclusive production of ρ0ρ0 mesons was measured at COMPASS by scattering 160 GeV/c muons off transversely polarised protons and deuterons. The measured asymmetry is sensitive to the nucleon helicity-flip generalised parton distributions EqEq, which are related to the orbital angular momentum of quarks in the nucleon. The Q2Q2, xBjxBj and pT2 dependence of AUTsin(ϕ−ϕS) is presented in a wide kinematic range: 1(GeV/c)2
