Measurement of the form factors of charged kaon semileptonic decays

A measurement of the form factors of charged kaon semileptonic decays is presented, based on $4.4 \times 10^{6}$ $K^\pm \to \pi^0 e^\pm \nu_e$ ($K^\pm_{e3}$) and $2.3 \times 10^{6}$ $K^\pm \to \pi^0 \mu^\pm \nu_\mu$ ($K^\pm_{\mu3}$) decays collected in 2004 by the NA48/2 experiment. The results...

Sumario:A measurement of the form factors of charged kaon semileptonic decays is presented, based on $4.4 \times 10^{6}$ $K^\pm \to \pi^0 e^\pm \nu_e$ ($K^\pm_{e3}$) and $2.3 \times 10^{6}$ $K^\pm \to \pi^0 \mu^\pm \nu_\mu$ ($K^\pm_{\mu3}$) decays collected in 2004 by the NA48/2 experiment. The results are obtained with improved precision as compared to earlier measurements. The combination of measurements in the $K^\pm_{e3}$ and $K^\pm_{\mu3}$ modes is also presented.
