Model-independent confirmation of the Z(4430)Z(4430) state / LHCb collaboration
The decay B0ψ(2S)K+πB0ψ(2S)K+π is analyzed using 3 fb13 fb1 of pppp collision data collected with the LHCb detector. A model-independent description of the ψ(2S)πψ(2S)π mass spectrum is obtained, using as input the KπKπ mass spectrum and angular distribution derived directly from data, without requiring a theoretical description of resonance shapes or their interference.

Measurement of the inelastic pppp cross-section at a centre-of-mass energy of s=7s=7 TeV / LHCb Collaboration
The cross-section for inelastic proton-proton collisions, with at least one prompt long-lived charged particle of transverse momentum pT>0.2pT>0.2 GeV/cc in the pseudorapidity range 2.0<η<4.52.0<η<4.5, is measured by the LHCb experiment at a centre-of-mass energy of s=7s=7 TeV. The cross-section in this kinematic range is determined to be σaccinel=55.0±2.4σaccinel=55.0±2.4 mb within the spectrometer acceptance with an experimental uncertainty that is dominated by systematic contributions.

Measurement of B+cB+c production in proton-proton collisions at s=8s=8 TeV / LHCb Collaboration
Production of B+cB+c mesons in proton-proton collisions at a center-of-mass energy of 8 TeV is studied with data corresponding to an integrated luminosity of 2.0 fb12.0 fb1 recorded by the LHCb experiment. The ratio of production cross-sections times branching fractions between the B+cJ/ψπ+B+cJ/ψπ+ and B+J/ψK+B+J/ψK+ decays is measured as a function of transverse momentum and rapidity in the regions 0<pT<20GeV/c0<pT<20GeV/c and 2.0<y<4.52.0<y<4.5.

A search for time-integrated CP violation in the Cabibbo-suppressed decay D0ππ+π0D0ππ+π0 is performed using for the first time an unbinned model-independent technique known as the energy test. Using proton-proton collision data, corresponding to an integrated luminosity of 2.0 fb11 collected by the LHCb detector at a centre-of-mass energy of ss = 8 TeV, the world's best sensitivity to CP violation in this decay is obtained [...]

Precision luminosity measurements at LHCb / LHCb collaboration
Measuring cross-sections at the LHC requires the luminosity to be determined accurately at each centre-of-mass energy ss. In this paper results are reported from the luminosity calibrations carried out at the LHC interaction point 8 with the LHCb detector for ss = 2.76, 7 and 8 TeV (proton-proton collisions) and for sNNsNN = 5 TeV (proton-lead collisions).
