Abstract

n a preliminary version of the NA48 experiment at the CERN SPS, in which an iron-scintillator sandwich calorimeter was used as a photon detector, the ratio of KL → πμνγ and KL → πμν decays was measured. The branching ratio BR(KL → πμνγ,E*γ ≥30 MeV)/(KL → πμν) is found to be (2.08 ± 0.17+0.16 -0.21) × 10-3, where the first error is statistical and the second systematic. The result is in agreement with theoretical predictions.
