Nucleon-Nucleon Interaction Models and Non-Locality

Abstract

Abstract. The effect of non-locality in the NN interaction models is examined. It is shown that this feature can explain differences in predictions made from models evidencing a difference with this respect. This is done for both static and dynamical observables, taking into account that a non-local term can be transformed away by performing a unitary transformation. Some results for the deuteron form factors, the A(Q 2 ) structure function and the T20(Q 2 ) tensor polarization are given as an example. A few cases where discrepancies cannot be explained are also considered. They point to differences in the models as for the deuteron asymptotic normalizations, AS and AD, which are not affected by the present analysis.
