First Measurement of K/sub NN/ in the Reaction Vector Pp Yields Vector D pi exp + at 800 MeV

摘要

Recent controversy over the existence of exotic strangeness-zero resonances in the two nucleon system has emphasized the fact that this system presents an inherently multi-channel problem just above pion production threshold. Exotic two-nucleon states, if they exist, are certainly very inelastic. This leads to the conclusion that measurements of pion production channels to roughly the same extent and accuracy as measurements of nucleon-nucleon elastic scattering are necessary for fuller understanding of the two nucleon system. The results presented should provide valuable input to these multi-channel models needed to understand the two nucleon system. 6 references. (ERA citation 09:045041)
