Pentaquarks in SU(3) quark model

Abstract

Based on the flavor SU(3) symmetry, we classify all the possible pentaquark baryons made of four quarks and one antiquark. In particular, we present possible multiplets of pentaquarks, their interactions with mesons, and the mass relations within a multiplet. We also study the pentaquark decays in the generalized OZI rule.
