Study of B0s → J/ψπ+π−K+K− decays
(Springer, 2021-02)
The decays B0s → J/ψπ+π−K+K− are studied using a data set corresponding to an integrated luminosity of 9 fb−1, collected with the LHCb detector in proton-proton collisions at centre-of-mass energies of ...
Identification of beauty and charm quark jets at LHCb
(IOPscience, 2015-06)
Identification of jets originating from beauty and charm quarks is important for measuring Standard Model processes and for searching for new physics. The performance of algorithms developed to select ...

Determination of the quark coupling strength |Vub| using baryonic decays
(Nature, 2015-07)
In the Standard Model of particle physics, the strength of the couplings of the b quark to the u and c quarks, |Vub| and |Vcb|, are governed by the coupling of the quarks to the Higgs boson. Using data ...
Observations of B0 s → ψ(2S)η and B0 (s) → ψ(2S)π+π− decays
(Elsevier, 2013-06)
First observations of the B0s→ψ(2S)η,B0→ψ(2S)π+π− and B0s→ψ(2S)π+π− decays are made using a dataset corresponding to an integrated luminosity of 1.0 fb−1 collected by the LHCb experiment in proton–proton ...
Observation of Multiplicity Dependent Prompt χc1(3872) and ψ(2S) Production in pp Collisions
(2021-03)
The production of χc1(3872) and ψ(2S) hadrons is studied as a function of charged particle multiplicity in pp collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity ...
Search for long-lived particles decaying to e ± μ∓ ν
(Springer, 2021-03)
Long-lived particles decaying to e±μ∓ν, with masses between 7 and 50GeV/c2 and lifetimes between 2 and 50ps, are searched for by looking at displaced vertices containing electrons and muons of opposite ...
First Observation of the Decay B0s→K−μ+νμ and a Measurement of |Vub|/|Vcb|
(American Physical Society, 2021-02)
The first observation of the suppressed semileptonic B0s→K−μ+νμ decay is reported. Using a data sample recorded in pp collisions in 2012 with the LHCb detector, corresponding to an integrated luminosity ...
