AI Article Synopsis

  • * The study used a data sample from 2011 with an integrated luminosity of 0.35 fb-1.
  • * It also provided the most precise measurement of CP violation in B0 meson decays to K±π∓ pairs, showing a value of -0.088±0.011(stat)±0.008(syst) with a significance greater than 6σ.

Article Abstract

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 Bs0} mesons to K±π∓ pairs, ACP(Bs0→Kπ)=0.27±0.08(stat)±0.02(syst), with a significance of 3.3σ. Furthermore, we report the most precise measurement of CP violation in the decays of B0 mesons to K±π∓ pairs, ACP(B0→Kπ)=-0.088±0.011(stat)±0.008(syst), with a significance exceeding 6σ.
