A new measurement of the branching ratio of K-S -> gamma gamma

Abstract:
The decay rate of K(S) → γγ has been measured with the NA48 detector at the CERN SPS. A total of 149 K(S) → γγ events have been observed. The branching ratio is determined to be (2.58 ± 0.36(stat) ± 0.22(sys)) x 10-6. (C) 2000 Elsevier Science B.V.
