Title:     EFFECTIVE THEORY FOR LOW-ENERGY NUCLEAR DENSITY FUNCTIONALS

Abstract: Effective theories are used in different domain of physics with tremendous success. I consider a possible implementation of the ideas of the effective theory to construct new classes of nuclear density functionals. The well-known regularization scheme based on regularized delta interactions is set for the typical scale of low-energy nuclear phenomena. The role played by these regularized interactions is to smear away the details of nuclear densities, thus leaving us with only those parts that vary smoothly. By regularizing the contact pseudopotentials, the smooth variations of the nuclear density can be described within a controlled expansion of a gradually increasing precision. I will show the convergence results of the expansion to metadata obtained by employing the standard Gogny functional. The perfect convergence achieved is a promising hint for future direct adjustments to the actual experimental data.
