Searches for the Light Invisible Axion-Like Particle in K*+ *> *p*+*p*0a Decay / A.S.Sadovsky, V.N.Bychkov, G.D.Kekelidze, V.M.Lysan, B.Zh.Zalikhanov, [a.o.] // The European Physical Journal C [Electronic resource]. – 2024. – Vol. 84, No. 3. – P. 266. – URL: https://doi.org/10.1140/epjc/s10052-024-12444-y. – Bibliogr.: 266.
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*+→π*+π*0a. No signal is observed, the upper limits for the branching ratio of the decay are calculated. The 90% confidence level upper limit is changing from 2.5⋅10&sup(−6) to 2⋅10&sup(−7) for the ALP mass from 0 to 200 MeV/c*2, except for the region of π*0 mass, where the upper limit is 4.4⋅10&sup(−6).
ОИЯИ = ОИЯИ (JINR)2024
Спец.(статьи,препринты) = С 346.5б - Свойства К-мезонов: масса, спин, четность, схемы и времена распадов
