Constraining the symmetry energy with heavy-ion collisions and Bayesian analyses
Abstract
Efficiency corrected single ratios of neutron and proton spectra in central and collisions at 120 MeV/u are combined with double ratios to provide constraints on the density and momentum dependencies of the isovector mean-field potential. Bayesian analyses of these data reveal that the isoscalar and isovector nucleon effective masses, are strongly correlated. The linear correlation observed in yields a nearly independent constraint on the effective mass splitting . The correlated constraint on the standard symmetry energy, $$S_0$$ and the slope, L at saturation density yields the values of symmetry energy MeV at a sensitive density of .
