520 | _ | _ | |a Azimuthal single- and double-spin asymmetries measured at HERMES in semi-inclusive leptoproduction of pions, charged kaons, protons, and antiprotons from a transversely polarized hydrogen target are presented. The results of a re-analysis of the previously published Collins and Sivers asymmetries, extended to include protons and antiprotons as well as an extraction in a multi-dimensional binning and enlarged phase space, is reported along with the corresponding results for the remaining single- and double-spin asymmetries associated to the semi-inclusive deep-inelastic scattering process with a transversely polarized target. Among those results, significant non-vanishing ${\rm cos}(\phi − \phi_s)$ modulations provide evidence for a sizable worm-gear distribution $𝑔_{1𝑇}$ . Most of the other modulations are found to be consistent with zero with the notable exception of large ${\rm sin}(𝜙_s)$ modulations for charged pions and positively charged kaons. |
