Abstract

Measured ratios of decay rates for R_Ke3/K2π, R _Kμ3/K2π and R_Kμ3/Ke3 are presented. These measurements are based on K^± decays collected in a dedicated run in 2003 by the NA48/2 experiment at CERN. The results obtained are R _Ke3/K2π = 0.249±0.0009 (stat)±0.0004 (syst)and R_Kμ3/K2π = 0.1637±0.0006 (stat)±0.0003 (syst). Using the PDG average for the K^±→π ^±π⁰ normalisation mode, both values are found to be larger than the current values given by the particle data book and lead to a larger magnitude of the |V_us| CKM element than previously accepted. When combined with the latest particle data book value of |V_ud|, the result is in agreement with unitarity of the CKM matrix. In addition, a new measured value of R_Kμ3/Ke3 = 0.656±0.003(stat)±0. 001(syst) is compared to the semi-empirical predictions based on the latest form factor measurements.
