Possible $D\bar{D}$ and $B\bar{B}$ Molecular states in a chiral quark model

Abstract

We perform a systematic study of the bound state problem of $D\bar{D}$ and $B\bar{B}$ systems by using effective interaction in our chiral quark model. Our results show that both the interactions of $D\bar{D}$ and $B\bar{B}$ states are attractive, which consequently result in $I^G(J^{PC})=0^{+}(0^{++})$ $D\bar{D}$ and $B\bar{B}$ bound states.
