Measurement of the neutral D meson mixing parameters in a time-dependent amplitude analysis of the D0 →π+π-π0 decay Graugés Pous, Eugeni BABAR Collaboration Interaccions d'hadrons Simetria (Física) Hadron interactions Symmetry (Physics) 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 ( 4 S ) resonance, and correspond to an integrated luminosity of approximately 468.1     fb − 1 . The neutral D meson candidates are selected from D ∗ ( 2010 ) + → D 0 π + 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. 2018-01-29T12:06:12Z 2018-01-29T12:06:12Z 2016-06-28 2018-01-29T12:06:12Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1550-7998 https://hdl.handle.net/2445/119373 669775 eng Reproducció del document publicat a: https://doi.org/10.1103/PhysRevD.93.112014 Physical Review D, 2016, vol. 93, num. 11, p. 112014-1-112014-10 https://doi.org/10.1103/PhysRevD.93.112014 (c) American Physical Society, 2016 info:eu-repo/semantics/openAccess 1 p. application/pdf American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
