摘要：

The Brazilian Nuclear Potential (BP) [1, 2], a relativistic and covariant O(q(4)) chiral expansion of the two-pion exchange NN potential had its configuration space content fitted by simple formulas [3]. In order to test the applicability of this parametrized potential, the d pi(+) production in pp scattering at threshold was studied and the results were compared to the ones given by Reid 93 and v 18 potentials. The results are very close to the v 18 potential, repeating what had happen in a previous work [4].
