Title: Two-pion exchange contributions to the relativistic NN kernel: Peripheral scattering

Abstract

The relativistic one-boson-exchange model for NN scattering is extended by including two-pion exchange (TPE) contributions in the kernel. We develop the formalism for the evaluation of the TPE diagrams within the relativistic quasipotential approach. The peripheral partial waves in elastic NN scattering are studied within this model. The TPE interactions contain a strongly attractive isoscalar-scalar component which requires a low value of the cutoff parameter: {lambda}=650-800 MeV. With this prescription, the peripheral waves can be reasonably described.
