Using data from LHCb corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions, measurements of several CP observables are performed. First observations are obtained of the suppressed ADS decay B∓ → [π ∓K±π 0 ]Dπ ∓ and the quasi-GLW decay B∓ → [K+K−π 0 ]Dπ ∓. The results are interpreted in the context of the unitarity triangle angle γ and related parameters.26 p.application/pdfeng(c) American Physical Society, 2015HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsStudy of C P violation in B∓→D h∓ (h =K ,π ) with the modes D →K∓π±π0 , D →π+π-π0 and D →K+K-π0info:eu-repo/semantics/article6567752022-06-07info:eu-repo/semantics/openAccess
