CP violation in $B^{0}_{(s)}\rightarrow h^{+}h^{-}$

An important test of the Standard Model is represented by the charmless charged two-body $b$-hadron decays to final states with kaons and pions. In fact the $C\!P$ asymmetries measured using these decays are sensitive to new physics beyond the Standard Model since the decay amplitudes receive contributions from loop-level diagrams with magnitudes similar to those from tree-level transitions. We report the most recent results on the charmless \textit{b}-hadron two-body decays obtained by the LHCb experiment using the data collected in Run~1 (3 fb$^{-1}$).
