We study the 
decay to 
based on the chiral unitary approach, which generates the X(3720) resonance, and we make predictions for the 
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 mass distribution with no free parameters.
