Measurement of charged kaon semileptonic decay branching fraction using ISTRA+ detector

The ratio of branching fractions for and K − → π − π 0 decays has been measured using the ISTRA+ spectrometer. The result of our measurement is the following: Using the current PDG value for the K 2π branching fraction, this result leads to the measured K e 3 branching fraction of Br( K e 3 ) = 0.05...
