SPD -在NICA对撞机上使用极化质子和氘核束的自旋物理项目

SPD - the Spin Physics Project with Polarized Proton and Deuteron Beams at the NICA Collider

A. Guskov

摘要:

在JINR(俄罗斯杜布纳)未来的NICA对撞机上进行的SPD实验旨在研究纵向和横向极化质子和氘核碰撞中的核子自旋结构和极化现象,其能量为$\sqrt{s}$至27 GeV,亮度为10 $^{32}$ cm $^{-2}$ s $^{-1}$。测量Drell-Yan对、粲偶素和瞬发光子产生中的不对称性可以提供一个获得核子中全套领先扭曲TMD PDF的途径。实验装置计划作为一个通用的4 $π$探测器的广泛的物理任务。

英文摘要:

The SPD experiment at the future NICA collider at JINR (Dubna, Russia) aims to investigate the nucleon spin structure and polarization phenomena in 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$^{-1}$. Measurement of asymmetries in the Drell-Yan pairs, charmonium and prompt photon production can provide an access to the full set of leading twist TMD PDFs in nucleons. The experimental setup is planned as a universal 4$π$ detector for a wide range of physics tasks.
