Does the existence of f0 meson enlarge the K+ π0π0π0 e+ decay probability?
Abstract
We estimate a possible contribution of the two-pion system f0(500) wide resonance to the decay probability of the super rare decay K+ 3π0 e+ . 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.
