First evidence of direct CP violation in charmless two-body decays of B0s mesons

Using a data sample corresponding to an integrated luminosity of 0.35  fb−1 collected by LHCb in 2011, we report the first evidence of CP violation in the decays of B0s mesons to K±π∓ pairs, ACP(B0s→Kπ)=0.27±0.08(stat)±0.02(syst), with a significance of 3.3σ. Furthermore, we report the most precise...
