Description
A search has been made for photons from the reactions K-p → Λγ and K-p → Σ0γ produced by K-stopping in a liquid hydrogen target. No signal from these reactions was found; upper limits on the branching ratios are K-p → Λγ/K-p → anything <= 4 x 10-4, K-p → Σ0γ/K-p → anything <= 4 x 10-3. The first of these is in conflict with a theoretical prediction using recent values for coupling constants and scattering amplitudes. This may reflect the influence of the Λ(1405) on the radiative capture. (orig.)
