Abstract
We present the latest results from the LHCb experiment on the measurement of the time-dependent \(C\!P\) asymmetries in \(B^0 \rightarrow \pi ^+ \pi ^-\) and \(B^0_{\mathrm{s}} \rightarrow K^+ K^-\) in addition to the time-integrated \(C\!P\) asymmetries in \(B^0 \rightarrow K^+ \pi ^-\) and \(B^0_{\mathrm{s}} \rightarrow \pi ^+ K^-\). The analysis uses a data sample of pp collisions corresponding to an integrated luminosity of 3.0 fb\(^{-1}\), collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV. Evidence for \(C\!P\) violation in \(B^0_{\mathrm{s}} \rightarrow K^+ K^-\) is found for the first time with a significance of 4.0 standard deviations.
