Abstract / Bemerkung
Exclusive production of $\rho^0$ mesons was studied at the COMPASS experimentby scattering 160 GeV/$c$ muons off transversely polarised protons. Fivesingle-spin and three double-spin azimuthal asymmetries were measured as afunction of $Q^2$, $x_{Bj}$, or $p_{T}^{2}$. The $\sin \phi_S$ asymmetry isfound to be $-0.019 \pm 0.008(stat.) \pm 0.003(syst.)$. All other asymmetriesare also found to be of small magnitude and consistent with zero withinexperimental uncertainties. Very recent calculations using a GPD-based modelagree well with the present results. The data is interpreted as evidence forthe existence of chiral-odd, transverse generalized parton distributions.
