The breathing-mode giant monopole resonance is studied within the framework of the relativistic mean-field (RMF) theory. Using a broad range of parameter sets, an analysis of constrained incompressibility and excitation energy of isoscalar monopole states in finite nuclei is performed. It is shown that the non-linear scalar self-interaction considerably. It is observed that dynamical surface pr...

We discuss SU(2) chiral sigma model in the nuclear matter using mean field approach at high density. In this model we include a dynamically generated isoscalar vector field and higher order terms in scalar field. With inclusion of these, we reproduce the empirical values of the nuclear matter saturation density, binding energy and the nuclear incompressibility. The desirable value of incompress...
