Description
The SPD experiment will operate at one of the two interaction points of the NICA at JINR. The collider will deliver polarised beams for $pp$ and $dd$ collisions with center-of-mass energies up to $\sqrt{s} = 27\,\mathrm{GeV}$ and $\sqrt{s_{NN}} = 13.5\,\mathrm{GeV}$, respectively. The main objective of the experiment is to investigate both polarized and unpolarized gluonic structures of protons and deuterons. Transverse momentum dependent distribution functions related to gluons --- including helicity, Sivers, Boer-Mulders distributions, and gluon transversity specifically in deuterons --- will be studied using measurements of open charm, charmonium, and prompt photon production. Beyond its core objectives, the experimental program encompasses investigations into diverse facets of Quantum Chromodynamics (QCD). This presentation will provide an overview of the physics program, describe the experimental setup, and discuss the current status of the project.
