D0 Anti-D0 Mixing Results From BaBar with D0 to K+ Pi- Pi0
We present a preliminary search for D{sup 0}-{bar D}{sup 0} mixing using the decays D{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0}, additionally presenting Dalitz-plot distributions and a measurement of the branching ratio for this mode. A new tagging technique is used to produce the doubly Cabibbo-suppressed Dalitz plot, which in turn is used to motivate the method used for the D-mixing search. We analyze 230.4 fb{sup -1} of data collected from the BABAR detector at the PEP-II collider. Assuming CP conservation, we find R{sub M} < 0.054% with 95% confidence, and we estimate that the data are consistent with no mixing at a 4.5% confidence level. We present D-mixing results both with and without the assumption of CP conservation.
