Abstract
We present a Bayesian analysis of the Landau mass within the extended \(\sigma \)–\(\omega \) model for neutron star matter. To this purpose, we consider the mass measurement of the object PSR 0740+6620, the tidal deformability estimation from the GW170817 and the mass-radius estimate of PSR J0030+0451 by NICER. Using Landau mass as free parameter of the theory, we tested the prediction power to find the best value for this nuclear parameter of the Bayesian method.
