LHCb: Observation of CP violation in $B^{\pm} \to DK^{\pm}$ decays at LHCb
An analysis of $B^+ \to DK^+$ and $B^+ \to D\pi^+$ decays is presented where the D meson is reconstructed in the two-body final states: $K^+\pi-, K^+K^-, \pi^+\pi^-$ and $\pi^+K^-$. Using 1.0 fb$^{-1}$ of LHCb data, measurements of several observables are made including the first observation of...

| description | An analysis of $B^+ \to DK^+$ and $B^+ \to D\pi^+$ decays is presented where the D meson is reconstructed in the two-body final states: $K^+\pi-, K^+K^-, \pi^+\pi^-$ and $\pi^+K^-$. Using 1.0 fb$^{-1}$ of LHCb data, measurements of several observables are made including the first observation of the suppressed mode $B^+ \to DK^+, D \to \pi^+K^-$. CP violation in $B^+ \to DK^+$ decays is observed with 5.8 $\sigma$ significance. |
