Exclusive production of $\\rho^0$ 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 $Q^2$, $x_{Bj}$, or $p_{T}^{2}$. The $\\sin \\phi_S$ asymmetry is found to be $-0.019 \\pm 0.008(stat.) \\pm 0.003(syst.)$. 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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.66743.v1/t1","@type":"Dataset","description":"Single-spin azimuthal asymmetries for a transversely (T) polarised target and unpolarised (U) beam.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.66743.v1/t2","@type":"Dataset","description":"Single-spin azimuthal asymmetries for a transversely (T) polarised target and unpolarised (U) beam.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.66743.v1/t3","@type":"Dataset","description":"Single-spin azimuthal asymmetries for a transversely (T) polarised target and unpolarised (U) beam.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.66743.v1/t4","@type":"Dataset","description":"Double-spin azimuthal asymmetries for a transversely (T) polarised target and a longitudinally (L) polarised beam.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.66743.v1/t5","@type":"Dataset","description":"Double-spin azimuthal asymmetries for a transversely (T) polarised target and a longitudinally (L) polarised beam.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.66743.v1/t6","@type":"Dataset","description":"Double-spin azimuthal asymmetries for a transversely (T) polarised target and a longitudinally (L) polarised beam.","name":"Table 6"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1257385?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/66743"}],"inLanguage":"en","name":"Transverse target spin asymmetries in exclusive $\\rho^0$ muoproduction","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1257385?version=1","version":1}
