|Abstract: ||The first observations of the rare decays KS ! 0e+e− and KS ! 0μ+μ− have been made
by the NA48/1 collaboration at the CERN SPS accelerator. From high intensity KS data
collected during the 2002 run, clean signals of 7 KS ! 0e+e− events and 6 KS ! 0μ+μ−
events were observed, giving branching ratio measurements of BR(KS ! 0e+e−) = 5.8+2.9
10−9 and BR(KS ! 0μ+μ−) = 2.9+1.5
× 10−9. These results constrain the indirect CP
violating component of the corresponding KL decays. Other recent results from NA48 are
