Observation of $K^{+} \to π^{+} π^{0} π^{0} γ$ decay

S. N. Filippov, E. N. Gushchin, A. A. Khudyakov +29

The $K^{+} \to π^{+} π^{0} π^{0} γ$ decay is observed by the OKA collaboration. The branching ratio is measured to be $(4.1 \pm 0.9 (s t a t) \pm 0.4 (sy s t)) \times 1 0^{- 6}$ . The branching…

Searches for the light invisible axion-like particle in $K^{+} \to π^{+} π^{0} a$ decay

A. S. Sadovsky, A. P. Filin, S. A. Akimenko +31

A high statistics data sample of the $K^{+}$ decays is recorded by the OKA collaboration. A missing mass analysis is performed to search for a light invisible pseudoscalar axion-li…
