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.

Hunting for $B\bar B$ molecular state $X_{b0}$ via radiative transition of $\Upsilon(10753)$
hep-ph 2026-05 unverdicted novelty 4.0

The decay Υ(10753) → γ X_b0 is predicted to have partial width 0.2-1.5 keV and branching fraction 10^{-6} to 10^{-5} for binding energies 0-10 MeV, dominated by B1(') meson loops.
