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

Abstract A high-statistics data sample of the $$K^{+}$$ 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 $$K^{+} \rightarrow \pi ^{+} \pi ^{0} a$$ K + → π + π 0 a . No signal is...
