A study on the Bose-Einstein correlations for triplets of same-sign pions is presented. The analysis is performed using proton-proton collisions at a centre-of-mass energy of s = 7 TeV, recorded by the LHCb experiment, corresponding to an integrated luminosity of 1.0 fb−1. For the first time, the results are interpreted in the core-halo model. The parameters of the model are determined in regions of charged-particle multiplicity. This measurement provides insight into the nature of hadronisation in terms of coherence, being consistent with the presence of coherent emission of pions.Observation of the $${{{\varLambda } ^0_{b}} \!\rightarrow {{J \hspace{-1.66656pt}/\hspace{-1.111pt}\psi }} {{\varXi } ^-} {{K} ^+} }$$ and $${{{{\varXi } ^0_{b}} \!\rightarrow {{J \hspace{-1.66656pt}/\hspace{-1.111pt}\psi }} {{\varXi } ^-} {{\pi } ^+} }}$$ decays

The first observation of the Ξb0 → J/ψΞ− π+ decay and the most precise measurement of the branching fraction of the Λb0 → J/ψΞ− K+ decay are reported, using proton-proton collision data from the LHCb experiment collected in 2016–2018 at a centre of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb−1. Using the Λb0 → J/ψΛ and Ξb0 → J/ψΞ− decays as normalisation channels, the ratios of branching fractions are measured to be B(Λb0 → J/ψΞ− K+)/B(Λb0 → J/ψΛ) = (1.17 ± 0.14 ± 0.08) × 10−2, B(Ξb0 → J/ψΞ− π+)/B(Ξb0 → J/ψΞ−) = (11.9 ± 1.4 ± 0.6) × 10−2, where the first uncertainty is statistical and the second systematicSearch for the decay $B^0 \rightarrow ϕϕ$
