Description

The Spin Physics Detector (SPD) at the Nuclotron based Ion Col- lider
fAcility (NICA) is designed to study nucleon spin structure in the three dimensions.
With capabilities to collide polarized protons (up to √s = 27 GeV) and deuterons
(up to √s = 13.5 GeV) with peak design luminosity 10^{32} cm^{−2} s^{−1} for
protons (an order of magnitude less for deuterons), the experiment will allow
measurements of cross-sections and spin asymmetries sensitive to the
un-polarized and various polarized (helicity, Sivers, Boer-Mulders) gluon
distributions inside the nucleons. Proposed asymmetry measurements in three
par- ticular channels (prompt photon, charmonia and open-charm meson
production) and their possible impacts in our present understanding of gluon spin
distributions will be presented.
