Search for the decay $K_{S} \to \pi^{0}e^{+}e^{-}$

A search for the decay $K_{S} \to \pi^{0}e^{+}e^{-}$ 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 $K_{S}$ beam, an upper limit for the branching fraction ${\rm B}(K_{S} \to \pi^{0}e^{+}e^{-}) < 1.4 \times 10^{-7}$ a...

Sumario:A search for the decay $K_{S} \to \pi^{0}e^{+}e^{-}$ 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 $K_{S}$ beam, an upper limit for the branching fraction ${\rm B}(K_{S} \to \pi^{0}e^{+}e^{-}) < 1.4 \times 10^{-7}$ at 90\% confidence level has been obtained.
