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…

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,…

A precise measurement of the direct CP violation parameter Re(epsilon'/epsilon)
NA48 Collaboration
The direct CP violation parameter Re(epsilon'/epsilon) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 mill…
