Abstract
The search for CP-violating KS3π0 decay was performed with SND detector at VEPP-2M e+e- collider. The total amount of data corresponding to 7 million produced KS mesons was analyzed. No candidate events were found, giving an upper limit of the decay branching ratio: Br(KS3π0) < 1.4·10-5 at 90% confidence level.
