Résumé

We present a new measurement of the branching ratio R of the decay K _L→ pi;^±e^∓ν, denoted as K^e3, relative to all charged KL decays with two tracks, based on data taken with the NA48 detector at the CERN SPS. We measure R=0.4978±0. 0035. From this we derive the Ke3 branching fraction and the weak coupling parameter |V_us| in the CKM matrix. We obtain |V_us|f+(0)=0. 2146±0.0016, where f+(0) is the vector form factor in the K_e3 decay.
