本文提出了一套完整的方位单自旋和双自旋不对称性，用于从横向极化的质子中产生介子、带电介子、质子和反质子。这些不对称性包括之前发表的Hermes关于Collins和Sivers不对称性的结果，对这些结果的分析已经扩展到包括质子和反质子，也包括在三维运动学仓储和扩大的相空间中的提取。对于与入射轻子束方向垂直的目标极化方向的半包含式深度非弹性散射过程的单光子交换近似中允许的其余四个单自旋和四个双自旋不对称，它们得到了相应的结果补充。在这些结果中，显著的非零CoS(ϕ−ϕS)调制为蜗轮(II)的相当大的分布提供了证据。除了对带电介子和K+的大SIN(ϕ，S)调制外，大多数其他的调制都与零一致。
A comprehensive set of azimuthal single-spin and double-spin asymmetries in semi-inclusive leptoproduction of pions, charged kaons, protons, and antiprotons from transversely polarized protons is presented. These asymmetries include the previously published HERMES results on Collins and Sivers asymmetries, the analysis of which has been extended to include protons and antiprotons and also to an extraction in a three-dimensional kinematic binning and enlarged phase space. They are complemented by corresponding results for the remaining four single-spin and four double-spin asymmetries allowed in the one-photon-exchange approximation of the semi-inclusive deep-inelastic scattering process for target-polarization orientation perpendicular to the direction of the incoming lepton beam. Among those results, significant non-vanishing cos (ϕ− ϕ S) modulations provide evidence for a sizable worm-gear (II) distribution,. Most of the other modulations are found to be consistent with zero with the notable exception of large sin (ϕ S) modulations for charged pions and K+.
