Coarse grained Potential analysis of neutron-proton and proton-proton scattering below pion production threshold

الأصل · EN

Using the delta-shell representation we present a successful fit to neutron-proton and proton-proton scattering data below pion production threshold. A detailed overview of the theory necessary to calculate observables with this potential is presented. A new data selection process is used to obtain the largest mutually consistent data base. The analysis includes data within the years 1950 to 2013. Using 46 parameters we obtain chi²/Ndata = 1.04 with Ndata = 6713 including normalization data. Phase shifts with error bars are provided.
