Updated analysis of NN elastic scattering to 3 GeV

In our previous analysis of nucleon-nucleon (NN) elastic scattering data [1], the upper energy limit was extended from 2.5 to 3.0 GeV in the laboratory kinetic energy, Tp, in order to accomodate higher-energy proton-proton (pp) scattering measurements from SATURNE II at Saclay and the EDDA Collaboration at COSY. Comparisons were made with the direct amplitude reconstruction (DAR) and partial-wave analysis (PWA) study of Ref. [2], which gave amplitudes to 2.7 GeV. In some cases, where the DAR allowed 2 distinct solutions, our energy-dependent and single-energy results were seen to follow different sets of DAR amplitudes. With additional precise measurements, it was expected that these descrepancies would be removed. Such data have now appeared and our fits have changed substantially as a result. In the following, we will list those data recently added to our database. After a brief reminder of the differences between the PWA and DAR techniques, we will give our latest fit results. Some of the changes have been quite large, and these are discussed in light of the constraints imposed by the earlier Saclay DAR results. Finally, we summarize the status of the NN problem and consider what further work may be expected.
