Description
CP violation in charmless charged two-body B decays provides a way to measure the CKM angle gamma from decays involving loop diagrams. Using data collected by LHCb in 2011 we reconstruct a large sample of such decay modes of B hadrons. We present measurements of direct CP violation in B(s) → K pi decays, which are the most precise presently available, as well as of direct and mixing-induced CP violation in B0 → pi+ pi- and Bs → K+ K- decays, performed for the first time at a hadron collider and the first time ever, respectively.
