Open AccessPrecise tests of low energy QCD from \(\mbox {\)\mathrm {K}_{\mathrm {e}4}\(}\) decay properties
We report results from the analysis of the \(\mbox {\)\mathrm {K}^{\pm}\(}\rightarrow \pi^{+} \pi^{-} \mathrm{e}^{\pm} \nu\) ( ...

Open AccessMeasurement of the direct emission and interference terms and search for CP violation in the decay K ±→π ± π 0 γ
We report on the measurement of the direct emission (DE) and interference (INT) terms of the K ±→π ± π 0 ...

Open AccessNew high statistics measurement of Ke4 decay form factors and ππ scattering phase shifts
We report results from a new measurement of the Ke4 decay K±→π+π-e±ν by the NA48/2 collaboration at the CERN SPS, based on a partial sample of more than 670 000 Ke4 decays in both charged modes collected in 2003....

Measurements of charged kaon semileptonic decay branching fractions K±→π0μ±ν and K±→π0e±ν and their ratio
In an earlier paper [1], the background for Ke3 was over estimated due to an erroneous calculation of the electron identification efficiency. The correct ratios of the partial widths involving this channel are ...
