“…A relativistic complex multirank separable potential of the neutronproton system was proposed in Ref. [57,58]. The approach we use here furnishing both relativity and inelasticity has already been exploited in the much higher energy range covering from ISR up to LHC, √ s = 25 − 7000GeV [59,60].…”

The repulsive short distance core is one of the main paradigms of nuclear physics which even seems confirmed by QCD lattice calculations. On the other hand nuclear potentials at short distances are motivated by high energy behavior where inelasticities play an important role. We analyze NN interactions up to 3 GeV in terms of simple coarse grained complex and energy dependent interactions. We discuss two possible and conflicting scenarios which share the common feature of a vanishing wave function at the core location in the particular case of Swaves. We find that the optical potential with a repulsive core exhibits a strong energy dependence whereas the optical potential with the structural core is characterized by a rather adiabatic energy dependence which allows to treat inelasticity perturbatively. We discuss the possible implications for nuclear structure calculations of both alternatives.

“…It should be also emphasized that the relativistic calculation of FSI has been performed within the BS approach using a relativistic separable potential for the first time. Recently the considered separable potentials [10,11] have been modified to take into account inelastic processes (production of various mesons) occurring in the NN interaction at high energies [22]. However, energies of nucleons do not reach the inelasticity threshold under kinematic conditions [13].…”

The electrodisintegration of the deuteron is considered within a relativistic model of nucleon-nucleon interaction based on the Bethe-Salpeter approach with a separable interaction kernel. The exclusive cross section is calculated within the impulse approximation under various kinematic conditions. Final state interactions between the outgoing nucleons are taken into account. The comparison of nonrelativistic and relativistic calculations is presented. Partial-wave states of the neutron-proton pair with total angular momentum J = 0, 1 are considered.

The exclusive electrodisintegration of the deuteron is considered within the Bethe-Salpeter approach with a separable interaction kernel. The relativistic kernel of nucleon-nucleon interaction is obtained considering the phase shifts in the elastic neutron-proton scattering and properties of the deuteron. The differential cross section is calculated within the impulse approximation under several kinematic conditions of the Bonn experiment. Final state interactions between the outgoing nucleons are taken into account. Partial-wave states of the neutron-proton pair with total angular momentum J = 0, 1 are considered.
