Measurement of charged kaon semileptonic decay branching fractions and their ratio at the NA-48/2 experiment at CERN
Measurements of the ratios of charged kaon decay rates for Ke3/K2 π, K μ 3/K2 π and K μ 3/Ke3 are presented. These measurements are based on charged kaon decays collected in a dedicated run in 2003 by the NA48/2 experiment at CERN. The results obtained are Ke3/K2 π = 0.2470 ± 0.0009 ( stat ) ± 0.000...
