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

The upper limit on the $K^{+} \to π^{0} π^{0} π^{0} e^{+} ν$ decay

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

A search for the $K^{+} \to π^{0} π^{0} π^{0} e^{+} ν$ 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 upp…

Search for heavy neutrino in $K^{+} \to μ^{+} ν_{H}$ decay

A. S. Sadovsky, V. F. Kurshetsov, A. P. Filin +38

A high statistics data sample of the $K^{+} \to μ^{+} ν_{μ}$ decay was accumulated by the OKA experiment in 2012. The missing mass analysis was performed to search for the decay channel…
