The azimuthal cosϕ and cos2ϕ modulations of the distribution of hadrons produced in unpolarized semi-inclusive deep-inelastic scattering of electrons and positrons off hydrogen and deuterium targets have been measured in the HERMES experiment. For the first time these modulations were determined in a four-dimensional kinematic space for positively and negatively charged pions and kaons separately, as well as for unidentified hadrons. These azimuthal dependences are sensitive to the transverse motion and polarization of the quarks within the nucleon via, e.g., the Cahn, Boer-Mulders and Collins effects.

On the physics potential to study the gluon content of proton and deuteron at NICA SPD
自旋物理探测器（SPD）是一个未来的多用途实验，预计将在NICA对撞机上运行，目前正在联合核研究所（JINR，杜布纳，俄罗斯）建造。该实验的物理方案是基于纵向和横向极化质子和氘核的碰撞，其能量为$\sqrt{s}$至27 GeV，亮度为10 $^{32}$ cm $^{-2}$ s $^{-1}$。SPD将作为一个通用的设施，使用不同的互补探针，如：charmonia，开放的魅力，并提示光子生产过程的核子的非极化和极化胶子内容的综合研究。这项工作的目的是对SPD可能解决的物理目标进行彻底的审查，强调相关的理论方面，并在可用时讨论相关的实验结果。在不同的相关现象中，特别注意的是通过测量特定的单自旋和双自旋不对称性来研究核子中的胶子螺旋度、胶子Sivers和Boer-Mulders函数，以及氘核中的胶子横变性分布。
