Negative-parity NN resonances and extraneous states

Description

Angular momentum excitations of six quarks in a bag give a rich resonance structure in the NN channel above P/sub lab/ approx. = 1.3 GeV/c. Some states occur with quantum numbers foreign to NN, which we refer to as extraneous states. The lowest negative-parity states are an (NN)1P1 resonance and two extraneous I = 0 states with J/sup P/ = 0- and 2-, all around 2.2 GeV. The latter two states mainly decay in NNπ. The lowest (NN)3F3 resonance lies at M = 2.34 GeV
