We have studied the contribution of the state X(3930), coming from the interaction of the DD¯ and Ds+Ds- channels, to the B→ KJ/ ψω decay. The purpose of this work is to offer a complementary tool to see if the X(3930) state observed in the DD channel is the same or not as the X(3960) resonance claimed by the LHCb Collaboration from a peak in the Ds+Ds- mass distribution around threshold. We present results for what we expect in the J/ ψω mass distribution in the B→ KJ/ ψω decay and conclude that a clear signal should be seen around 3930MeV. At the same time, finding no extra resonance signal at 3960MeV would be a clear indication that there is not a new state at 3960MeV, supporting the hypothesis that the near-threshold peaking structure p...
