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…

Search for the decay
A. Lai
A search for the decay has been made using the NA48 detector at the CERN SPS. Using data collected in 1999 during a 40-hour run with a high-intensity beam, an u…

Precise measurements of the KS->gamma gamma and KL->gamma gamma decay rates
A. Lai
The KS->gamma gamma decay rate has been measured with the NA48 detector using a high intensity short neutral beam from the CERN SPS. The measured branching ratio BR(KS->gamma gamma…
