Transverse target spin asymmetries in exclusive ?0 muoproduction
Original language description
Exclusive production of ?0 mesons was studied at the COMPASS experiment by scattering 160 GeV/c muons off transversely polarised protons. Five single-spin and three double-spin azimuthal asymmetries were measured as a function of Q2, xBj, or p_T^2. The sin ?S asymmetry is found to be -0.019?0.008(stat.)?0.003(syst.)-0.019?0.008(stat.)?0.003(syst.). All other asymmetries are also found to be of small magnitude and consistent with zero within experimental uncertainties. Very recent calculations using a GPD-based model agree well with the present results. The data is interpreted as evidence for the existence of chiral-odd, transverse generalized parton distributions.
