Description
P-wave pentaquarks with strangeness +1, I=0, and JP=1/2+ are studied in the nonrelativistic quark model with instanton induced interaction (III). We present their mass splittings and orbital-spin-isospin-color structures. It is found that decompositions of the wave functions are sensitive to III, while the mass splittings are insensitive. The decay of the lowest energy pentaquark, Θ+, is found to be suppressed when the contribution of III is increased. Spin structure of the dominant components of the wave function is studied
