Abstract
|
Results for the first measurement of the inclusive branching and CP asymmetry of the charmless 3-body decay B(sup +) (yields) K(sup +)(pi)(sup 0)(pi)(sup 0) are presented. The analysis uses a data sample with an integrated luminosity of 429.0 fb(sup -1), recorded by the BABAR detector at the PEP-II asymmetric B Factory. This sample corresponds to 470.9 (+-) 2.8 million B(bar B) pairs. Measurements of the branching fractions (B) and CP asymmetries (A(sub CP)) of some of the intermediate resonances in the K(sup +)(pi)(sup 0)(pi)(sup 0) Dalitz plot are also presented.
