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

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-like particle (ALP) \(a\) in the decay \(K^{+} \to \pi^{+} \pi^{0} a\). No signal is observed, the upper limits for the...
