Abstract

This project consists on the development of works in three topics of hadron physics, all involving effective theories and renormalization methods. The first problem is the study of nuclei and hadronic matter using effective interactions obtained with the similarity renormalization group and the investigation of its infrared limit. The second problem is the application of the renormalization group to the chiral NN interactions at N3LO, where we can investigate the evolution of the interactions with the Callan-Symanzik flow equations. The third problem is the use of the NJL model to study the magnetized quark matter and to compare renormalization methods. (AU)
