Description
Understanding the properties of strongly interacting matter, especially its Equation of State, in the regime of high net-baryon density is one of the goals in the physics of relativistic heavy-ion collisions. One powerful probe is directed flow, which is highly sensitive to the pressure gradients in the evolving system. Light clusters, like deuterons, are expected to provide a stronger signal than, e.g., protons. Besides, since light nuclei are composite, their formation mechanism (e.g. coalescence) and their sensitivity to nucleon dynamics can influence signals observed in an experiment.
In this talk, we present the first measurement of directed flow of deuterons in Xe + Cs(I) collisions at a beam kinetic energy of 3.8A GeV, collected with the BM@N experiment. We place these results in context by comparing to existing world data.
