A search for the decay KS →π0 e+e− 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 KS beam, an upper limit for the branching fraction B(KS →π0 e+e−) <1.4×10^(−7) at 90% confidence level has been obtained.

Abstract
A search for the decay KS →π0 e+e− 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 KS beam, an upper limit for the branching fraction B(KS →π0 e+e−) <1.4×10^(−7) at 90% confidence level has been obtained.File in questo prodotto:
