Nuclear matter saturation in a relativistic chiral theory and QCD susceptibilities

Abstract

We study a chiral relativistic theory of nuclear matter aimed at the desciption of both the binding and saturation properties and the QCD properties, quark condensate and QCD susceptibilities. For this purpose the nucleon scalar response of the quark-meson coupling model is introduced in the linear sigma model. The consequences for the nuclear and the QCD scalar susceptibilities are discussed.Comment: 9 pages, 3 figures, sumitted to Physical Review
