On the renormalization of nucleon-nucleon interaction by one rho-meson exchange

Abstract

The nature of the nucleon-nucleon interaction has always been a subject of intense discussion in the low-energy hadron physics literature. In the last decades, the research related to chiral perturbation theory developed by Gasser, Leutwyler and Weinberg have gained attention due to the advances in using chiral symmetry to describe nuclear interactions. In this work we discuss aspects of the renormalizability of the interaction between two nucleons by one ρ and one π mesons exchange. The results give us important hints on the required short-distance cancellations of the singular tensor potential due to pion exchange.
