Description
We report on the measurement of the branching fraction of the rare decay
K+- -> pi+- gamma gamma using the full NA48/2 dataset of more than 5000
reconstructed decays from the full NA48/2 data set.
From the spectrum of the invariant gamma gamma mass, the decay
parameter c^ can be extracted with unprecedented precision.
