Search for the rare decay K+-->π+γ
Abstract
We have performed a search for the angular-momentum forbidden decay K+-->π+γ with the E787 detector at BNL. No events were observed in the π+ kinematic region around 227 MeV/c. An upper limit on the branching ratio for the decay is determined to be 3.6×10-7 at 90% confidence level.
