(Blai) Picatoste Olloqui, Eduardo Potterat, Cédric Rives Molina, Vicente José Ruiz, Hugo (Ruiz Pérez) Vázquez Gómez, Ricard Vilasis-Cardona, Xavier LHCb Collaboration Física de partícules Experiments Particle physics Experiments A measurement of the C P asymmetry in B 0 → K * 0 μ + μ − decays is presented, based on 1.0     fb − 1 of p p collision data recorded by the LHCb experiment during 2011. The measurement is performed in six bins of invariant mass squared of the μ + μ − pair, excluding the J / ψ and ψ ( 2 S ) resonance regions. Production and detection asymmetries are removed using the B 0 → J / ψ K * 0 decay as a control mode. The integrated C P asymmetry is found to be − 0.072 ± 0.040 ( stat ) ± 0.005 ( syst ) , consistent with the standard model. 2019-05-20T14:37:56Z 2019-05-20T14:37:56Z 2013-01-17 2019-05-20T14:37:56Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1103/PhysRevLett.110.031801 Physical Review Letters, 2013, vol. 110, num. 3, p. 031801 https://doi.org/10.1103/PhysRevLett.110.031801 cc by (c) CERN; LHCb Collaboration, 2013 http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
