Measurement of the Radiative Ke3 Branching Ratio

NA48 collaboration

We present a measurement of the relative branching ratio of the decay KL -> pi e nu gamma (Ke3gamma) with respect to KL-> pi e nu (gamma) (Ke3+Ke3gamma) decay. The result is based…

Measurement of K^0_e3 form factors

NA48 collaboration

The semileptonic decay of the neutral K meson, KL -> pi e nu (Ke3), was used to study the strangeness-changing weak interaction of hadrons. A sample of 5.6 million reconstructed ev…

Measurement of the branching ratio of the decay KL -> pi e nu and extraction of the CKM parameter |Vus|

NA48 collaboration

We present a new measurement of the branching ratio R of the decay KL -> pi e nu (Ke3), relative to all charged KL decays with two tracks, based on data taken with the NA48 detecto…

Search for CP violation in K0 -> 3 pi0 decays

NA48 Collaboration

Using data taken during the year 2000 with the NA48 detector at the CERN SPS, a search for the CP violating decay K_S -> 3 pi0 has been performed. From a fit to the lifetime distri…

Measurement of the Xi0 -> Lambda gamma Decay Asymmetry and Branching Fraction

A. Lai

In data taken with the NA48 experiment at the CERN SPS in 1999, 730 candidates of the weak radiative hyperon decay Xi0 -> Lambda gamma have been found with an estimated background…
