Abstract

In this paper the results obtained by the LHCb experiment in the sector of charmless charged two-body decays of b hadrons are reviewed. Using a data sample corresponding to an integrated luminosity of 0.37 fb^-1 collected in 2011, LHCb measured the relative branching ratios of the decays (where H_b can be either a B⁰, B _s ⁰, or hadron and h ^(′) stands for , K or p. Furthermore, using the full data sample collected in 2011, corresponding to 1.0 fb^-1 of integrated luminosity, LHCb measured the direct CP asymmetries of the and decays.
