Search for the decay $K_{s} \to \pi^{0}\gamma\gamma$

Abstract : A search for the decay K_S -> pi0gammagamma 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 K_S, an upper limit for the branching ratio BR (K_S -> pi0gammagamma,z = 0.2) 3.3 x 10-7 has been obtained at 90% confidence level, where z = m^2_gammagamma/m^2_K_0.
