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:
