Measurement of branching fractions and direct CP asymmetries in charmless charged two-body B decays at LHCb

Review

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 \( H_b\rightarrow h^{+} h^{\prime -}\) decays (where Hb can be either a B0, B s 0, or \( \Lambda_{b}\) hadron and h (′) stands for \( \pi\), 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 \( B^{0} \rightarrow K^{+}\pi^{-}\) and \( B_{s}^{0}\rightarrow \pi^{+} K^{-}\) decays.
