Prospects for $B_{(d,s)} \to h^{+}h^{-}$ at LHCb

LHCb will collect large samples of $B_{(d)}$ and $B_{(s)}$ decays. Combining the CP-violating observables of the decays $B_{(d)} \to \pi^{+}\pi^{-}$ and $B_{(s)} \to K^{+}K^{-}$ it is possible to extract the $\gamma$ angle of the unitarity triangle. The selection of these decays within the current LHCb simulation framework is outlined and the expected annual event yields and background-to-signal ratios are quoted. Then, the results of a study on the sensitivity that LHCb can achieve for the corresponding CP-violating observables are presented.
