Searches for CP violation and pi pi S wave in the Dalitz-plot analysis of D-0 ->pi(+)pi(-)pi(0) Academic Article uri icon

abstract

  • In e+e- collisions recorded using the CLEO II.V detector we have studied the Cabibbo suppressed decay of D0+-0 with the initial flavor of the D0 tagged by the decay D*+D0+. We use the Dalitz-plot analysis technique to measure the resonant substructure in this final state and observe and nonresonant contributions by fitting for their amplitudes and relative phases. We describe the S wave with a K-matrix formalism and limit this contribution to the rate to be <2.5%@95% confidence level, in contrast to the large rate observed in D++-+ decay. Using the amplitudes and phases from this analysis, we calculate an integrated CP asymmetry of 0.01-0.07+0.090.05. 2005 The American Physical Society.
