A search for the dark photon in the OKA experiment
The OKA Collaboration, A. S. Sadovsky, A. P. Filin +35
A search for the massless dark photon in the decay is performed with the OKA detector exposed to 17.7 GeV/c RF separated secondary beam of t…

Does the existence of meson enlarge the decay probability?
E. K. Karkaryan, V. F. Obraztsov, M. I. Vysotsky
We estimate a possible contribution of the two-pion system wide resonance to the decay probability of the super rare decay . We vary the width of t…

On the decay
E. K. Karkaryan, K. V. Kiselev, V. F. Obraztsov +2
The OKA Collaboration has obtained a new upper limit on the decay probability which is 65 times lower than the one currently listed by PDG. However it…
