LHCP / Time-dependent CP violation in B0_(s) -> hh

The time-dependent CPV direct and mixing-induced asymmetries in B^0->\pi \pi and B_s ->K K decays have been measured at the LHCb experiment using data collected during Run1 at centre-of-mass energies of 7 and 8 TeV, corresponding to 3fb^-1. The data set was also used for a measurement of time-integrated CP asymmetries in B^0->K \pi and B_s->\pi K decays. The results obtained supersede those of B factories /with much higher precision. No other experiment has ever measured CP violation in B_s -> K K decays. The measurements of the time-integrated CP asymmetries are the most precise from a single experiment to date.
