Measurement of the neutral D meson mixing parameters in a time-dependent amplitude analysis of the D^0→π^+π^−π^0 decay
Abstract
We perform the first measurement on the D^0−D^0 mixing parameters using a time-dependent amplitude analysis of the decay D^0→π^+π^−π^0. The data were recorded with the BABAR detector at center-of-mass energies at and near the Υ(4S) resonance, and correspond to an integrated luminosity of approximately 468.1 fb^(−1). The neutral D meson candidates are selected from D^∗(2010)^+→D^0π^+_s decays where the flavor at the production is identified by the charge of the low-momentum pion, π^+_s. The measured mixing parameters are x=(1.5±1.2±0.6)% and y=(0.2±0.9±0.5)%, where the quoted uncertainties are statistical and systematic, respectively.
