Flavor structure of pentaquark baryons in quark model

Abstract

The flavor SU(3) group structure of pentaquark baryons which form $1$, $8$, $10$, $\overline{10}$, $27$, and $35$ multiplets is investigated in quark model. The flavor wave functions of all the pentaquark baryons are constructed in SU(3) quark model and their Yukawa interactions with meson octet are obtained in general and in the special case of the octet-antidecuplet ideal mixing with the OZI rule. The mass sum rules of pentaquark baryons are also discussed.
