Observation of the B0s→η′η′ Decay
(American Physical Society, 2015-07-28)
The first observation of the B0s→η′η′ decay is reported. The study is based on a sample of proton-proton collisions corresponding to 3.0 fb−1 of integrated luminosity collected with the LHCb detector. ...
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 ...
Measurement of CP Violation in B0→J/ψK0S Decays
(American Physical Society, 2015-07-14)
Measurements are presented of the CP violation observables S and C in the decays of B0 and ¯B0 mesons to the J/ψK0S final state. The data sample corresponds to an integrated luminosity of 3.0 fb−1 ...
Search for the Λ 0b → Λη ′ and Λ 0b → Λη decays with the LHCb detector
(Springer, 2015-09-01)
A search is performed for the as yet unobserved baryonic Λ 0b → Λη ′ and Λ 0b → Λη decays with 3 fb−1 of proton-proton collision data recorded by the LHCb experiment. The B0 → K 0s η ′ decay is used ...
Measurement of the Z+b-jet cross-section in pp collisions at s√ = 7 TeV in the forward region
(Springer, 2015-01-13)
The associated production of a Z boson or an off-shell photon γ * with a bottom quark in the forward region is studied using proton-proton collisions at a centre-of-mass energy of 7 TeV. The Z bosons ...
Study of the rare B0s and B0 decays into the π+ π− μ+ μ− final state
(Elsevier, 2015-04-09)
A search for the rare decays B0s→π+π−μ+μ−and B0→π+π−μ+μ−is performed in a data set corresponding to an integrated luminosity of 3.0fb−1collected by the LHCb detector in proton–proton collisions at ...
Study of B0→D*−π+π−π+ and B0→D*−K+π−π+ decays
(American Physical Society, 2013-05-03)
Using proton-proton collision data collected by the LHCb experiment at √s=7 TeV, corresponding to an integrated luminosity of 1.0 fb−1, the ratio of branching fractions of the B0→D*−π+π−π+ decay ...

Measurement of b hadron production fractions in 7 TeV pp collisions
(American Physical Society, 2012-02-24)
Measurements of b hadron production ratios in proton-proton collisions at a center-of-mass energy of 7 TeV with an integrated luminosity of 3 pb−1 are presented. We study the ratios of strange B meson ...
