Search for lepton-flavour-violating decays of Higgs-like bosons / LHCb Collaboration
A search is presented for a Higgs-like boson with mass in the range 45 to 195 GeV/c2 decaying into a muon and a tau lepton. The dataset consists of proton-proton interactions at a centre-of-mass energy of 8 TeV, collected by the LHCb experiment, corresponding to an integrated luminosity of 2 fb1. [...]

Measurement of the forward energy flow in pp collisions at s= 7 TeV / LHCb Collaboration
The energy flow created in pp collisions at s=7 TeV is studied within the pseudorapidity range 1.9<eta<4.9 with data collected by the LHCb experiment. The measurements are performed for inclusive minimum-bias interactions, hard scattering processes and events with an enhanced or suppressed diffractive contribution. [...]

Exclusive J/ψ and ψ(2S) production in pp collisions at s=7 TeV / LHCb Collaboration
Exclusive J/ψ and ψ(2S) vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be σppJ/ψ(μ+μ)(2.0<ημ±<4.5)=307±21±36 pb, σppψ(2S)(μ+μ)(2.0<ημ±<4.5)=7.8±1.3±1.0 pb, where the first uncertainties are statistical and the second are systematic.
