High statistic measurement of the K- -> pi0 e- nu decay form-factors
Phys.Lett.B589:111-117,2004 The decay K- -> pi0 e- nu is studied using in-flight decays detected with the ISTRA+ spectrometer. About 920K events are collected for the analysis. The lambda+ slope parameter of the decay form-factor f+(t) in the linear approximation (average slope) is measured: lamb...
