Abstract
A regularization scheme that explicitly separates vacuum contributions from medium effects is applied to a Nambu-Jona-Lasinio model with diquark interactions and in beta equilibrium. We perform a comparison of this proposed scheme with the more traditional one, where no separation of vacuum and medium effects is done. Our results point to both qualitative and quantitative important differences between these two methods, in particular regarding the phase structure of the model in the cold and dense nuclear matter case.
