Derivative-coupling models and the nuclear-matter equation of state

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

The equation of state of saturated nuclear matter is derived using two different derivative-coupling Lagrangians. We show that both descriptions are equivalent and can be obtained from theσ −ω model through an appropriate rescaling of the coupling constants. We introduce generalized forms of this rescaling to study the correlations amongst observables in infinite nuclear matter, in particular, the compressibility and the effective nucleon mass.
