$B \to h^+h^{‘-}$ Prospects at LHCb

The LHCb experiment will collect very large samples of $B$-mesons decaying to charmless two-body final states. The combined measurements of the $B^0 \to \pi^+\pi^-$ and $B^0 _s \to K^+K^-$ time-dependent CP asymmetries allow a determination for the unitarity triangle angle $\gamma$, under the assumption of U-spin flavour symmetry. We present the status of the LHCb simulated analysis of the charged two-body charmless modes.
