Search for heavy neutral leptons in $W^{+} \to μ^{+} μ^{\pm} jet$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +980

A search is performed for heavy neutrinos in the decay of a $W$ boson into two muons and a jet. The data set corresponds to an integrated luminosity of approximately $3.0 \text{ fb…

LHCb collaboration, R. Aaij, C. Abellán Beteta +866

A narrow pentaquark state, $P_{c} (4312)^{+}$ , decaying to $J / ψ p$ is discovered with a statistical significance of $7.3 σ$ in a data sample of $Λ_{b}^{0} \to J / ψ p K^{-}$ decays which is an or…

Precision measurement of the mass and lifetime of the Xi_b^- baryon

LHCb collaboration, R. Aaij, B. Adeva +699

We report on measurements of the mass and lifetime of the Xi_b^- baryon using about 1800 Xi_b^- decays reconstructed in a proton-proton collision data set corresponding to an integ…
