Abstract

The LHCb experiment is designed to perform flavour physics measurements at the Large Hadron Collider. Using data collected during the 2010 run, we reconstruct a sample of Hb → h+h− decays, where Hb can be either a B0 meson, a B0s meson or a Λb baryon, while h and h' stand for π, K or p. We provide preliminary values of the direct CP asymmetries of the neutral B0 and B0s mesons ACP (B0 → K+π−) = −0.074 ± 0.033(stat.) ± 0.008(syst.) and ACP (B0s → π+K−) = 0.15 ± 0.19(stat.) ± 0.02(syst.).
