Measurement of time-dependent $CP$ violation in charmless two-body $B$ decays

Using an integrated luminosity of 0.69~fb$^{-1}$ collected by LHCb in 2011, we report measurements of direct and mixing-induced $C\!P$ violation in $B^0\to\pi^+\pi^-$ and $B^0_s\to K^+K^-$ decays. We obtain \begin{equation*} \begin{split} A^{\rm dir}_{\pi\pi} = 0.11 \pm 0.21 \pm 0.03,\\ A^{\rm mix}...
