A Bayesian framework is introduced to constrain the density dependence of the Equation of State (EoS) for nuclear matter. The EoS is inferred using existing measurements of elliptic flow and the mean transverse kinetic energy of protons in the beam energy range of √sNN = 2−10 GeV. Tight constraints are obtained for densities up to 4 times the nuclear saturation density. However, the results are highly sensitive to the choice of observables, highlighting the need for consistent, high-precision measurements in this energy range.
