Study of K+ →π0e+νeγ decay with OKA setup

Results of study of the K+ → π0e+νγ decay at OKA setup are presented. 16889 events of this decay have been observed. The branching ratio with cuts E*γ > 10 MeV, 0.6 < cosΘ*eγ < 0.9 is calculated R=Brk+→π0e+veyBrK+→π0e+ve=0.574±0.010star.±0.021syst.×10−2. For the asymmetry Aξ we get Aξ = -0....
