Measurement of D0 ->omega eta Branching Fraction with CLEO-c Data

Abstract

Using CLEO-c data, we confirm the observation of D0 ->omega eta by BESIII. In the Dalitz Plot of D0 -> Kshort eta pi0, we find a background in the Kshort(->pipi)pi0 projection with a m(pipipi0) equal to the omega(782) mass. In a direct search for D0 -> (omega eta) we find a clear signal and measure BF(D0 ->omega eta) = (1.78+/-0.19+/-0.14) x 10**(-3), in good agreement with BESIII.
