A sample of kinematically identified K+→π+π0 decays obtained with the E949 detector was used to search for the helicity-suppressed decay π0→νν̄ resulting in an upper limit of 2.7×10-7 at 90% confidence level. The upper limit is also applicable to π0 decays into unknown weakly-interacting particles.
