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…

Measurement of the $η_{c} (1 S)$ production cross-section in $pp$ collisions at $s = 13$ TeV

LHCb collaboration, R. Aaij, C. Abellán Beteta +913

Using a data sample corresponding to an integrated luminosity of $2.0 f b^{- 1}$ , collected by the LHCb experiment, the production of the $η_{c} (1 S)$ state in proton-proton collisions…

Observation of a narrow pentaquark state, $P_{c} (4312)^{+}$ , and of two-peak structure of the $P_{c} (4450)^{+}$

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…

Observation of an excited $B_{c}^{+}$ state

LHCb collaboration, R. Aaij, C. Abellán Beteta +848

Using $pp$ collision data corresponding to an integrated luminosity of $8.5 fb^{- 1}$ recorded by the LHCb experiment at centre-of-mass energies of $s = 7$ , $8$ and…

Measurement of $B^{+}$ , $B^{0}$ and $Λ_{b}^{0}$ production in $p Pb$ collisions at $s_{NN} = 8.16 TeV$

LHCb Collaboration, R. Aaij, C. Abellán Beteta +842

The production of $B^{+}$ , $B^{0}$ and $Λ_{b}^{0}$ hadrons is studied in proton-lead collisions at a centre-of-mass energy per nucleon pair of $s_{NN} = 8.16 TeV$ record…

Measurement of the mass difference between neutral charm-meson eigenstates

LHCb Collaboration, R. Aaij, C. Abellán Beteta +842

We report a measurement of the mass difference between neutral charm-meson eigenstates using a novel approach that enhances sensitivity to this parameter. We use $2.3 \times 1 0^{6}$ $…
