Does the existence of $f_{0}$ meson enlarge the $K^{+} \to I ¨ ^{0} I ¨ ^{0} I ¨ ^{0} e^{+} I^½$ decay probability?

E. K. Karkaryan, V. F. Obraztsov, M. I. Vysotsky

We estimate a possible contribution of the two-pion system $f_{0} (500)$ wide resonance to the decay probability of the super rare decay $K^{+} \to 3 I ¨ ^{0} e^{+} I^½$ . We vary the width of t…

On the $K^{+} \to I ¨ ^{0} I ¨ ^{0} I ¨ ^{0} e^{+} I^½$ decay

E. K. Karkaryan, K. V. Kiselev, V. F. Obraztsov +2

The OKA Collaboration has obtained a new upper limit on the $K^{+} \to I ¨ ^{0} I ¨ ^{0} I ¨ ^{0} e^{+} I^½$ decay probability which is 65 times lower than the one currently listed by PDG. However it…
