Prospects of Open-Charm Asymmetry Measurements at the SPD

The Spin Physics Detector (SPD) at the Nuclotron based Ion Collider fAcility (NICA) is designed to study nucleon spin structure in the three dimensions. At design energy, the leading mechanism of charm meson pair production in proton–proton collisions is the gluon fusion. At the SPD, charmed mesons can be detected via their hadronic decay channels. While these measurements are challenging due to orders of magnitude larger hadronic background, we demonstrate the capacity to obtain asymmetry measurements that can make an impact on the present understanding of gluon Transverse Momentum Dependent (TMD) distributions inside protons.
