Abstract: (Elsevier)

We have searched for the decay KS→3π0 with the KLOE experiment at DAΦNE using data from e+e− collisions at a center of mass energy W∼mϕc2 for an integrated luminosity L=450pb−1 . The search has been performed with a pure KS beam obtained by tagging with KL interactions in the calorimeter and detecting six photons. We find an upper limit for the branching ratio of 1.2×10−7 at 90% C.L.
