Measurement of the form factors of charged kaon semileptonic decays

Abstract A measurement of the form factors of charged kaon semileptonic decays is presented, based on 4.4 × $ 10^{6} $K± → π0e±νe (Ke3±) and 2.3 × $ 10^{6} $K± → π0μ±νμ (Kμ3±) decays collected in 2004 by the NA48/2 experiment. The results are obtained with improved precision as compared to earlier m...

The results are obtained with improved precision as compared to earlier measurements. The combination of measurements in the Ke3± and Kμ3± modes is also presented. Ausführliche Beschreibung
