QCD susceptibilities and nuclear matter saturation in a chiral theory: inclusion of pion loops
We derive the equation of state of symmetric nuclear matter in a relativistic theory with $\sigma$ and $\omega$ exchange. We take a chiral version of this model which insures all the chiral constraints. Going beyond the mean field approach we introduce the effects of the pion loops. For the paramete...
