B→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 B0→π+π− and time-dependent CP asymmetries allow a determination of the unitarity triangle angle γ, under the assumption of U-spin flavour symmetry. We present the status of the LHCb simulated analysis of the charged two-body charmless modes.
