A. Delfino et al., DERIVATIVE-COUPLING MODELS AND THE NUCLEAR-MATTER EQUATION OF STATE, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 355(2), 1996, pp. 145-150
The equation of state of saturated nuclear matter is derived using two
different derivative-coupling Lagrangians. We show that both descript
ions are equivalent and can be obtained from the sigma - omega model t
hrough an appropriate rescaling of the coupling constants. We introduc
e generalized forms of this rescaling to study the correlations amongs
t observables in infinite nuclear matter, in particular, the compressi
bility and the effective nucleon mass.
