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…

Precise measurement of the decay

A. Lai

The decay rate of $\klpgg$ has been measured with the NA48 detector at the CERN SPS. A total of 2558 $\klpgg$ candidates have been observed with a residual background of 3.2%. The…

A Measurement of the K_S Lifetime

NA48 Collaboration

A measurement of the K_S lifetime is presented using data recorded by the NA48 experiment at the CERN-SPS during 1998 and 1999. The K_S lifetime is derived from the ratio of decay…

New measurements of the and masses

A. Lai, NA48 collaboration

New measurements of the and masses have been performed using decays to 3 with the NA48 detector at the CERN SPS. Using symmetric decays to reduce systematic effects,…
