Abstract

Using the NA48 detector at the CERN SPS, 31 K_S → π ⁰γγ candidates with an estimated background of 13.7 ± 3.2 events have been observed. This first observation leads to a branching ratio of BR(K_S → π⁰γγ) _z>0.2 = (4.9 ± 1.6_stat ± 0.9 _syst) × 10^-8 in agreement with Chiral Perturbation Theory predictions.
