Erratum
Received 23 July 2002; published 3 December 2002
In e+e- collisions using the CLEO detector, we have studied the decay of the D0 to the final state KS0π+π- with the initial flavor of the D0 tagged by the decay D*+→D0π+. We use the Dalitz technique to measure the resonant substructure in this final state and clearly observe ten different contributions by fitting for their amplitudes and relative phases. We observe a K*(892)+π- component which arises from doubly Cabibbo suppressed decays or D0-D0̅ mixing.
