Abstract

In this paper, recent results on the production of protons, deuterons and tritons from the BM@N experiment at NICA are presented. We discuss transverse momentum spectra and rapidity distributions of \(p\) , \(d\) , \(t\) from centrality selected Ar \(+\) nucleus collisions at the beam kinetic energy of 3.2 GeV per nucleon. The rapidity and mass dependence of the particle average transverse momentum is presented in different collision systems. The deuteron-to-proton ratio in rapidity bins is obtained in centrality selected collisions.
