Does the existence of $f_0$ meson enlarge the $K^+ \to π^0π^0π^0 e^+ ν$ decay probability?

We estimate a possible contribution of the two-pion system $f_{0} (500)$ wide resonance to the decay probability of the super rare decay $K^{+} \to 3 π^{0} e^{+} ν$ . We vary the width of the resonance from 0.01 MeV to 1000 MeV. We found that the contribution of the narrow resonance in a system of several final state particles into the decay probability is proportional to its width. However it never exceeds the value of the decay probability calculated on free final state particles neglecting the resonance contribution.
