Measurement of CP Violation in the Phase Space of B±→K+K−π± and B±→π+π−π± Decays Badalov, Alexey Calvo Gómez, Míriam Camboni, Alessandro Comerma Montells, Albert Garrido Beltrán, Lluís Graciani Díaz, Ricardo Graugés Pous, Eugeni Oyanguren Campos, Arantza de Pérez-Calero Yzquierdo, Antonio Picatoste Olloqui, Eduardo Potterat, Cédric Rives Molina, Vicente José Ruiz, Hugo (Ruiz Pérez) Ruiz Valls, Pablo Vilasis-Cardona, Xavier LHCb Collaboration Física de partícules Experiments Particle physics Experiments The charmless decays B ± → K + K − π ± and B ± → π + π − π ± are reconstructed in a data set of p p collisions with an integrated luminosity of 1.0     fb − 1 and center-of-mass energy of 7 TeV, collected by LHCb in 2011. The inclusive charge asymmetries of these modes are measured to be A C P ( B ± → K + K − π ± ) = − 0.141 ± 0.040     ( stat ) ± 0.018   ( syst ) ± 0.007 ( J / ψ   K ± ) and A C P ( B ± → π + π − π ± ) = 0.117 ± 0.021   ( stat ) ± 0.009   ( syst ) ± 0.007 ( J / ψ   K ± ) , where the third uncertainty is due to the C P asymmetry of the B ± → J / ψ K ± reference mode. In addition to the inclusive C P asymmetries, larger asymmetries are observed in localized regions of phase space. 2019-05-15T15:28:07Z 2019-05-15T15:28:07Z 2014-01-07 2019-05-15T15:28:07Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0031-9007 https://hdl.handle.net/2445/133208 645722 eng Reproducció del document publicat a: https://doi.org/10.1103/PhysRevLett.112.011801 Physical Review Letters, 2014, vol. 112, num. 1, p. 011801 https://doi.org/10.1103/PhysRevLett.112.011801 cc by (c) CERN; LHCb Collaboration, 2014 http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/openAccess 8 p. application/pdf American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
