We study the $B^0$ decay to $D^0 \bar D^0 K^0$ based on the chiral unitary model that generates the X(3720) resonance, and make predictions for the $D^0 \bar D^0$ invariant mass distribution. From the shape of the distribution, the existence of the resonance below threshold could be induced. We also predict the rate of production of the X(3720) resonance to the $D^0 \bar D^0$ mass distribution with no free parameters.

    Within the Bethe-Salpeter framework the authors find bound-state solutions for D anti-D pairs under all three coupling sets examined and for Ds anti-Ds pairs only in a restricted region, yielding predicted B+ branchin...
