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

Abstract

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 √ 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 4π detector for a wide range of physics tasks.
