Abstract

The relative decay probability B(φ → ηγ) = (1.259 ± 0.030 ± 0.059)% in the decay channel η → π⁺π^-π⁰ has been measured in an experiment using a spherical neutral detector in the VEPP-2M electron-positron storage ring. The result agrees with the tabulated value and with measurements of this probability using the spherical neutral detector in other η-meson decay channels.

agrees with the world average of 0.324 – 0.007 and is of comparable accuracy. From the sum of three measurements using the SND detector in different h -meson decay channels we can also obtain B(f ee)B(f hg ) = (3.848 – 0.036 – 0.070) · 10–6, B(f hg ) = (1.287 – 0.012 – 0.042)%, which is the most accurate measurement made using a single detector.
