Measurement of the ratio of branching fractions of the decays Λ0bψ(2S)ΛΛ0bψ(2S)Λ and Λ0bJ/ψΛ / LHCb Collaboration
Using pp collisions corresponding to 3fb1 integrated luminosity, recorded by the LHCb experiment at centre-of-mass energies of 7 and 8TeV, the ratio of branching fractions B(Λ0bψ(2S)Λ)/B(Λ0bJ/ψΛ)=0.513±0.023(stat)±0.016(syst)±0.011(B) is determined. The first uncertainty is statistical, the second is systematic and the third is due to the external branching fractions used..

Evidence for the rare decay Σ+pμ+μ / LHCb Collaboration
A search for the rare decay Σ+pμ+μ is performed using pp collision data recorded by the LHCb experiment at centre-of-mass energies s=7 and 8 TeV, corresponding to an integrated luminosity of 3fb1. An excess of events is observed with respect to the background expectation, with a signal significance of 4.1 standard deviations. [...]

Studies of the resonance structure in D0Kπ±π±π decays / LHCb Collaboration
Amplitude models are constructed to describe the resonance structure of D0Kπ+π+π and D0K+πππ+ decays using pp collision data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb experiment, corresponding to an integrated luminosity of 3.0fb1. The largest contributions to both decay amplitudes are found to come from axial resonances, with decay modes D0a1(1260)+K and D0K1(1270/1400)+π being prominent in D0Kπ+π+π and D0K+πππ+, respectively.
