Abstract
The first observations of the rare decays KS->pi0e+e- and KS->pi0mu+mu- 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->pi0e+e- events and 6 KS->pi0mu+mu- events were observed, giving branching ratio measurements of BR(KS->pi0e+e-) = 5.8 +2.9 -2.4 x 10^-9 and BR(KS->pi0mu+mu-) = 2.9 +1.5 -1.2 x 10^-9. These results constrain the indirect CP violating component of the corresponding KL decays. Other recent results from NA48 are also presented.
