Abstract
Searches for CP violation in the two-body decays D + (s) → h +π 0 and D + (s) → h +η (where h + denotes a π + or K+ meson) are performed using pp collision data collected by the LHCb experiment corresponding to either 9 fb−1 or 6 fb−1 of integrated luminosity. The π 0 and η mesons are reconstructed using the e +e −γ final state, which can proceed as three-body decays π 0 → e +e −γ and η → e +e −γ, or via the two-body decays π 0 → γγ and η → γγ followed by a photon conversion. The measurements are made relative to the control modes D + (s)→ K0 S h + to cancel the production and detection asymmetries. The CP asymmetries are measured to be
