NA48/2 results on charged semileptonic decays

We present preliminary results of the measurements of charged semileptonic decays $K^{\pm} \to \pi^{0}e^{\pm}\nu$ and $K^{\pm} \to \pi^{0}\mu^{\pm}\nu$. Both measurements indicate higher branching fractions for the corresponding decays than the current PDG values. Consequently, the CKM mixing matrix parameter $V_{us}$ will increase accordingly. In addition, a precision measurement of the ratio $Br(K^{\pm}_{\mu3})/Br(K^{\pm}_{e3})$ confirms the theoretical prediction.
