Study 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-π0

An analysis of the decays of B∓ → DK∓ and B∓ → Dπ∓ is presented in which the D meson is reconstructed in the three-body final states K∓π ±π 0 , π +π −π 0 and K+K−π 0 . Using data from LHCb corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions, measurements of several CP observables...

Descripción
Sumario:An analysis of the decays of B∓ → DK∓ and B∓ → Dπ∓ is presented in which the D meson is reconstructed in the three-body final states K∓π ±π 0 , π +π −π 0 and K+K−π 0 . 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.
