OKA ({{lang-ru|ОКА — Опыты с КАонами, literal translation "Observations of KAons"}}) is a particle physics detector experiment at the U-70 accelerator in the Institute for High Energy Physics located in Protvino near Moscow (Russia). OKA is specialized experiment with separated charge kaons beam. Superconducting high radio-frequency separator produces a beam of charged kaons intensity (4 ÷ 6) · 106 K for a cycle with momenta 12.5 and 18 GeV.[1] Experimental complex includes the decay volume with veto system, the wide-aperture magnetic spectrometer consists of a set of proportional chambers, straw tubes, drift tubes and hodoscope, the Cherenkov counters for charged particle identification, the electromagnetic calorimeter known as GAMS-2000 detector, the total absorption hadron calorimeter and the muon counters.[2]The research program of the experiment has the following items:[3]
The sensitivity of the OKA experiment will enable to observe decays with branching fractions of about 10−8.
