Direct and mixing-induced CP -violating asymmetries in B 0 s → K + K − decays are measured for the first time using a data sample of pp collisions, corresponding to an integrated luminosity of 1.0 fb −1 , collected with the LHCb detector at a centre-of-mass energy of 7 TeV. The results are C KK = 0.14 ± 0.11 ± 0.03 and S KK = 0.30 ± 0.12 ± 0.04, where the first uncertainties are statistical and the second systematic. The corresponding quantities are also determined for B 0 → π + π − decays to be C ππ = −0.38 ± 0.15 ± 0.02 and S ππ = −0.71 ± 0.13 ± 0.02, in good agreement with existing measurements.

The associated production of a W boson with a jet originating from either a light parton or heavy-flavor quark is studied in the forward region using proton-proton collisions. The analysis uses data corresponding to integrated luminosities of 1.0 and 2.0 fb −1 collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, respectively. The W bosons are reconstructed using the W → μν decay and muons with a transverse momentum, p T , larger than 20 GeV in the pseudorapidity range 2.0 < η < 4.5. The partons are reconstructed as jets with p T > 20 GeV and 2.2 < η < 4.2. The sum of the muon and jet momenta must satisfy p T > 20 GeV. The fraction of W þ jet events that originate from beauty and charm quarks is measured, along with the charge asymmetries of the W þ b and W þ c production cross sections. The ratio of the W þ jet to Z þ jet production cross sections is also measured using the Z → μμ decay. All results are in agreement with Standard Model predictions.
