$a The effect of inclusion of delta resonances in relativistic mean-field model with scaled hadron masses and coupling constants $f K. A. Maslov, E. E. Kolomeitsev, D. N. Voskresensky 330 $a © Published under licence by IOP Publishing Ltd.Knowledge of the equation of state of the baryon matter plays a decisive role in the description of neutron stars. With an increase of the baryon density the filling of Fermi seas of hyperons and Δ isobars becomes possible. Their inclusion into standard relativistic mean-field models results in a strong softening of the equation of state and a lowering of the maximum neutron star mass below the measured values. We extend a relativistic mean-field model with scaled hadron masses and coupling constants developed in our previous works and take into account now not only hyperons but also the Δ isobars. We analyze available empirical information to put constraints on coupling constants of Δs to mesonic mean fields. We show that the resulting equation of state satisfies majority of presently known experimental constraints. 463 -1
