Observation of $$K^{+} \rightarrow \pi ^{+}\pi ^{0}\pi ^{0}\gamma $$ K + → π + π 0 π 0 γ decay

Publikováno v: European Physical Journal C: Particles and Fields, Vol 84, Iss 4, Pp 1-6 (2024)

Abstract The $$K^{+} \rightarrow \pi ^{+}\pi ^{0}\pi ^{0}\gamma $$ K + → π + π 0 π 0 γ decay is observed by the OKA collaboration. About 60 events of the decay observed with signal:noise $$\approx 1$$ ≈ 1 . The branching ratio obtained by nor

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

Publikováno v: European Physical Journal C: Particles and Fields, Vol 84, Iss 3, Pp 1-6 (2024)

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 \p

Study of $$K^+ \rightarrow \pi ^{0} e^{+} \nu \gamma $$ K + → π 0 e + ν γ decay with OKA setup

Publikováno v: European Physical Journal C: Particles and Fields, Vol 81, Iss 2, Pp 1-5 (2021)

Abstract Results of a study of the $$K^+ \rightarrow \pi ^{0} e^{+} \nu \gamma $$ K + → π 0 e + ν γ decay at OKA setup are presented. More than 32,000 events of this decay are observed. The differential spectra over the photon energy and the pho

Thermal Condition in the Channels of Plate Heat Exchangers

Autor: Yu. V. Elistratova, A. S. Seminenko, V. A. Uvarov, V. A. Minko

Publikováno v: Proceedings of the Southwest State University. 26:22-38

Equipping heat points with plate-type heat exchangers is an integral structural element of the 3rd generation heat and power network and a component of the reliability of the heat supply system as a whole. It has been established that the optimizatio

Search for heavy neutrino in $$K^{+} \rightarrow \mu ^{+} \nu _{H}$$ K+→μ+νH decay

Publikováno v: European Physical Journal C: Particles and Fields, Vol 78, Iss 2, Pp 1-7 (2018)

Abstract A high statistics data sample of the $$K^{+}\rightarrow \mu ^{+}\nu _{\mu }$$ K+→μ+νμ decay was accumulated by the OKA experiment in 2012. The missing mass analysis was performed to search for the decay channel $$K^{+}\rightarrow \mu ^{
