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 $K^{+} \to I ¨ ^{+} I ¨ ^{0} I^^{3}$ is performed with the OKA detector exposed to 17.7 GeV/c RF separated secondary beam of t…

The upper limit on the $K^{+} \to I ¨ ^{0} I ¨ ^{0} I ¨ ^{0} e^{+} I^½$ decay

A. V. Kulik, S. N. Filippov, E. N. Gushchin +26

A search for the $K^{+} \to I ¨ ^{0} I ¨ ^{0} I ¨ ^{0} e^{+} I^½$ decay is performed by the OKA collaboration. The search is based on $3.65 \times 1 0^{9} K^{+}$ decays. No signal is observed. The…
