Nuclear Matter Equation Of State And Incompressibility In The Relativistic Density Dependent Hadron Field Theory

Nuclear matter equation of state and incompressibility are determined utilizing the relativistic density dependent Hadron field theory. Nuclear matter is studied at symmetric ground-state and at supernova collapse conditions, and pressure density of isentropic nuclear matter is determined as a function of the density at supernova collapse conditions. The value of the ground-state nuclear matter incompressibility is within the interval determined by isoscalar giant monopole resonance measurements and relativistic calculations. And the dependency of the coupling parameters on density leads to results closer to the results of calculations used in the study of supernova explosion than the results of other relativistic calculations.(author)
