SPD Experiment at NICA Collider: Status and Outlooks

In the near future the new NICA accelerator complex at JINR, Dubna will become operational with heavy-ion collisions. It is expected that the NICA collider at the second phase will provide intensive polarized and unpolarized proton–proton and deuteron–deuteron collisions that with the Spin Physics Detector (SPD) experiment could open new perspectives in the fields of high energy particle physics. The main goal of the SPD experiment is the comprehensive study of the unpolarized and polarized gluon content of the nucleon by charmonia production. In addition, there is a broad interesting program in hadron and nuclear physics. Presently, the SPD experiment at the NICA is at an advanced R $$\&$$ D stage and it is preparing to the construction phase.
