Abstract

ROCHA, Carlos A. da; HIGA, Renato  and  ROBILOTTA, Manoel R.. Brazilian relativistic O(q4) two-pion exchange nucleon-nucleon potential: parametrized version. Braz. J. Phys. [online]. 2007, vol.37, n.1a, pp. 75-79. ISSN 1678-4448.  http://dx.doi.org/10.1590/S0103-97332007000100023.

In our recent works we derived a chiral O(q4) two-pion exchange nucleon-nucleon potential (TPEP) formulated in a relativistic baryon (RB) framework, expressed in terms of the so called low energy constants (LECs) and functions representing covariant loop integrations. In order to facilitate the use of the potential in nuclear applications, we present a parametrized version of our configuration space TPEP.

Keywords : Two-pion exchange; Nucleon-nucleon potential; Relativistic baryon; Chiral symmetry; Chiral perturbation theory.
