摘要
We present a study of the NN system above pion threshold fully based on a constituent quark model. The calculation is performed in the framework of the coupled-channel method. A piNDelta vertex has been derived from the basic piqq vertex and it is probed in the P-33 piN partial wave. Taking into account the fact that this is a parameter-free calculation, the phase shifts and inelasticities are reasonably well reproduced.
