论文摘要
旋转物理探测器（SPD）是未来的多功能实验，可以预见在NICA Collider，该实验目前正在NICA Collider上进行，该实验目前正在核研究所联合研究所（Jinr，Dubna，俄罗斯）进行。实验的物理程序基于纵向和横向极化的质子和杜特龙的碰撞，$ \ sqrt {s} $最高27 GEV和Luminosity and Luminosity，最高10 $^{32} $ cm $^{ - 2} $^{ - 2} $ s $ s $^{ - 1} $。 SPD将作为核子的非极化和极化的Gluon含量的全面研究作为通用设施，使用不同的互补探针，例如：charmonia，open hopen harminia，open hable Charm和迅速的光子生产过程。这项工作的目的是对可能在SPD上解决的物理目标进行彻底审查，并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，通过测量特定的单个和双重自旋的测量，通过核子中的Gluon螺旋性研究，Gluon Sivers和Boer-Mulders在核子中起作用，以及Deuteron中的Gluon抗逆性分布。
The Spin Physics Detector (SPD) is a future multipurpose experiment foreseen to run at the NICA collider, which is currently under construction at the Joint Institute for Nuclear Research (JINR, Dubna, Russia). The physics program of the experiment is based on collisions of longitudinally and transversely polarized protons and deuterons at $\sqrt{s}$ up to 27 GeV and luminosity up to 10$^{32}$ cm$^{-2}$ s$^{-1}$. The SPD will operate as a universal facility for comprehensive study of unpolarized and polarized gluon content of the nucleon, using different complementary probes such as: charmonia, open charm, and prompt photon production processes. The aim of this work is to make a thorough review of the physics objectives that can potentially be addressed at the SPD, underlining related theoretical aspects and discussing relevant experimental results when available. Among different pertinent phenomena particular attention is drawn to the study of the gluon helicity, gluon Sivers and Boer-Mulders functions in the nucleon, as well as the gluon transversity distribution in the deuteron, via the measurement of specific single and double spin asymmetries.
