Dalitz Analysis of D0-->K0Sπ+π-
Abstract
In e+e- collisions using the CLEO detector, we have studied the decay of the D0 to the final state K0Sπ+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-D0¯ mixing.
