ADDENDUM 2 to P253 - A high sensitivity investigation of Ks and neutral hyperon decays using a modified Ks beam
No full textWe propose to use the NA48 detectrors and a slightly modified beam line to search for very rare Ks decays
ADDENDUM III (to Proposal P253/CERN/SPSC) for a Precision Measurement of Charged Kaon Decay Parameters with an Extended NA48 Setup
No full textA high statistics study of charged kaon decays, if carried out with correspondingly high systematic accuracy, has a potential to provide important new information about direct CP-violation, additional to that obtained from the decays of neutral kaons (epsilon'/epsilon).The proposal for such a study is described in this addendum tot the NA48 experimental programme. It makes use of a novel design for simultaneous K+/K- beams, in place of the present KL/KS beams

Precise tests of low energy QCD from K(e4) decay properties
No full textWe report results from the analysis of the K± → Π+Π-e±v (Ke4)decay by the NA48/2 collaboration at the CERN SPS, based on the total statistics of 1.13 million decays collected in 2003-2004. The hadronic form factors in the S- and P-wave and their variation with energy are obtained. The phase difference between the S- and P-wave states of the ππ system is accurately measured and allows a precise determination of a00 and a02, the I = 0 and I = 2 S-wave ππ scattering lengths: a00 = 0.2220 ± 0.0128 stat ± 0.0050stat ± 0.0037 th, a02 = -0.0432 ± 0.0086stat ± 0.0034syst ± 0.0028th. Combination of this result with the other NA48/2 measurement obtained in the study of K± → Π0Π0π± decays brings an improved determination of a00 and the first precise experimental measurement of a02, providing a stringent test of Chiral Perturbation Theory predictions and lattice QCD calculations. Using constraints based on analyticity and chiral symmetry, even more precise values are obtained: a00 = 0.2196 ± 0.0028 stat ± 0.0020stat and a02 = -0.0444 ± 0.0007stat ± 0.0005syst ± 0.0008chPT
