Study of charmonium production in b-hadron decays and first evidence for the decay B0sϕϕϕ / LHCb Collaboration
Using decays to ϕ-meson pairs, the inclusive production of charmonium states in b-hadron decays is studied with pp collision data corresponding to an integrated luminosity of 3.0fb1, collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV. Denoting by BCB(bCX)×B(Cϕϕ) the inclusive branching fraction of a b hadron to a charmonium state C that decays into a pair of ϕ mesons, ratios RC1C2BC1/BC2 are determined as Rχc0ηc(1S)=0.147±0.023±0.011, Rχc1ηc(1S)=0.073±0.016±0.006, Rχc2ηc(1S)=0.081±0.013±0.005, Rχc1χc0=0.50±0.11±0.01, Rχc2χc0=0.56±0.10±0.01 and Rηc(2S)ηc(1S)=0.040±0.011±0.004.

Test of lepton universality with B0K0+ decays / LHCb Collaboration
A test of lepton universality, performed by measuring the ratio of the branching fractions of the B0K0μ+μ and B0K0e+e decays, RK0, is presented. The K0 meson is reconstructed in the final state K+π, which is required to have an invariant mass within 100MeVc2 of the known K(892)0 mass. [...]

Search for long-lived scalar particles in B+K+χ(μ+μ) decays / LHCb Collaboration
A search for a long-lived scalar particle χ is performed, looking for the decay B+K+χ with χμ+μ in pp collision data corresponding to an integrated luminosity of 3fb1, collected by the LHCb experiment at centre-of-mass energies of s=7 and 8TeV. This new scalar particle, predicted by Hidden Sector models, is assumed to have a narrow width. [...]

Measurement of σ(ppb¯bX) at s=7 TeV in the forward region / LHCb Collaboration
Decays of b hadrons into final states containing a D0 meson and a muon are used to measure the b anti-b production cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC. In the pseudorapidity interval 2 < eta < 6 and integrated over all transverse momenta we find that the average cross-section to produce b-flavoured or anti-b-flavoured hadrons is (75.3 +/- 5.4 +/- 13.0) microbarns..

First observation of a baryonic B0s decay / LHCb Collaboration
We report the first observation of a baryonic B0s decay, B0sp¯ΛK, using proton-proton collision data recorded by the LHCb experiment at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3.0fb1. The branching fraction is measured to be B(B0sp¯ΛK)+B(B0sˉpΛK+)=[5.46±0.61±0.57±0.50(B)±0.32(fs/fd)]×106, where the first uncertainty is statistical and the second systematic, the third uncertainty accounts for the experimental uncertainty on the branching fraction of the B0p¯Λπ decay used for normalization, and the fourth uncertainty relates to the knowledge of the ratio of b-quark hadronization probabilities fs/fd..

First measurement of the CP-violating phase in B0sJ/ψ(e+e)ϕ decays / LHCb Collaboration
A flavour-tagged time-dependent angular analysis of B0sJ/ψϕ decays is presented where the J/ψ meson is reconstructed through its decay to an e+e pair. The analysis uses a sample of pp collision data recorded with the LHCb experiment at centre-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb1. [...]

Measurement of the CKM angle γ in the B0DK0 channel using self-conjugate DK0Sh+h decays / LHCb Collaboration
A model-independent study of CP violation in B0DK0 decays is presented using data corresponding to an integrated luminosity of 9fb1 collected by the LHCb experiment at centre-of-mass energies of s=7,8 and 13 TeV. The CKM angle γ is determined by examining the distributions of signal decays in phase-space bins of the self-conjugate DK0Sh+h decays, where h=π,K. [...]

Prompt and nonprompt J/ψ production and nuclear modification in pPb collisions at sNN=8.16 TeV / LHCb Collaboration
The production of J/ψ mesons is studied in proton-lead collisions at the centre-of-mass energy per nucleon pair sNN=8.16 TeV with the LHCb detector at the LHC. The double differential cross-sections of prompt and nonprompt J/ψ production are measured as functions of the J/ψ transverse momentum and rapidity in the nucleon-nucleon centre-of-mass frame. [...]

Study of CP violation in B0(s)toDK(892)0 decays with DKπ(ππ), ππ(ππ), and KK final states / LHCb Collaboration
A measurement of CP-violating observables associated with the interference of B0D0K(892)0 and B0¯D0K(892)0 decay amplitudes is performed in the D0Kπ±(π+π), D0π+π(π+π), and D0K+K final states using data collected by the LHCb experiment corresponding to an integrated luminosity of 9~fb1. CP-violating observables related to the interference of B0sD0¯K(892)0 and B0s¯D0¯K(892)0 are also measured, but no evidence for interference is found. [...]
