On the Scaling Properties of the Directed Flow of Protons in Au + Au and Ag + Ag Collisions at the Beam Energies of 1.23 and 1.58 A GeV

In the relativistic heavy ion collisions at the collision energies of a few GeV the strongly interacting matter is created at high baryon densities and relatively low temperatures. Azimuthal anisotropy of the produced particles provides a valuable insight into the properties of this form of matter. In this work, we discuss the scaling properties of directed flow of protons with system size as well as the collision energy.
