Directed flow of protons in Xe+CsI collisions at the energy of 3.8AGeV at BM@N (NICA)

Baryonic Matter at Nuclotron (BM@N) is a fixed-target experiment designed to probe the properties of the strongly interacting matter in the region of high baryon densities. In the beginning of 2023, BM@N has conducted the first physical experiment collecting several hundred millions of [Formula: see text] collisions at the beam energy of 3.8A[Formula: see text]GeV ([Formula: see text][Formula: see text]GeV). We report the preliminary results for the directed flow [Formula: see text] of protons with respect to the spectator symmetry plane from the first physics run at the BM@N facility. The results were compared with the existing data from previous measurements of directed flow in heavy-ion collisions at the beam energies of several GeV.
