A comprehensive set of azimuthal single-spin and double-spin asymmetries insemi-inclusive leptoproduction of pions, charged kaons, protons, andantiprotons from transversely polarized protons is presented. These asymmetriesinclude the previously published HERMES results on Collins and Siversasymmetries, the analysis of which has been extended to include protons andantiprotons and also to an extraction in a three-dimensional kinematic binningand enlarged phase space. They are complemented by corresponding results forthe remaining four single-spin and four double-spin asymmetries allowed in theone-photon-exchange approximation of the semi-inclusive deep-inelasticscattering process for target-polarization orientation perpendicular to thedirection of the incoming lepton beam. Among those results, significantnon-vanishing $\cos{\phi-\phi_S}$ modulations provide evidence for a sizableworm-gear (II) distribution, $g_{1T}$. Most of the other modulations are foundto be consistent with zero with the notable exception of large $\sin{\phi_S}$modulations for charged pions and positive kaons.
