First observation of the decay B0s→ϕK¯¯¯¯¯∗0
(Springer, 2013-10-28)
The first observation of the decay B0s→ϕK¯¯¯¯¯∗0 is reported. The analysis is based on a data sample corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions at s√=7 TeV, collected with ...
Study of χb meson production in pp collisions at s√=7 and 8TeV and observation of the decay χb(3P)→Υ(3S)γ
(Springer, 2014-10-08)
A study of χb meson production at LHCb is performed on proton–proton collision data, corresponding to 3.0 fb−1of integrated luminosity collected at centre-of-mass energies s√ = 7 and 8 TeV. The fraction ...
Measurement of ϒ production in pp collisions at s−−√=7 TeV
(Springer, 2012-06-07)
The production of ϒ(1S), ϒ(2S) and ϒ(3S) mesons in proton-proton collisions at the centre-of-mass energy of s√=7 TeV
is studied with the LHCb detector. The analysis is based on a data sample of 25 pb−1 ...
Measurement of CP observables in B 0 → DK ∗0 with D →K + K −
(Springer, 2013-03-12)
The decay B 0 → DK *0 and the charge conjugate mode are studied using 1.0 fb−1 of pp collision data collected by the LHCb experiment at s√=7 TeV in 2011. The CP asymmetry between the B 0 → DK *0 and the ...
First evidence of direct CP violation in charmless two-body decays of B0s mesons
(American Physical Society, 2012-05-16)
Using a data sample corresponding to an integrated luminosity of 0.35 fb−1 collected by LHCb in 2011, we report the first evidence of CP violation in the decays of B0s mesons to K±π∓ pairs, ...
Measurement of forward J/ψ production cross-sections in pp collisions at s√=13 TeV
(Springer, 2015-10-26)
The production of J/ψ mesons in proton-proton collisions at a centre-of-mass energy of s√=13 TeV is studied with the LHCb detector. Cross-section measurements are performed as a function of the transverse ...
Amplitude analysis and branching fraction measurement of ¯Bos → J/ψ K+K−
(American Physical Society, 2013-04-08)
An amplitude analysis of the final state structure in the ¯¯¯B0s→J/ψK+K− decay mode is performed using 1.0 fb−1 of data collected by the LHCb experiment in 7 TeV center-of-mass energy pp collisions ...
Measurement of the B+c meson lifetime using B+c→J/ψμ+νμX decays
(Springer, 2014-05-01)
The lifetime of the B+c meson is measured using semileptonic decays having a J/ψ meson and a muon in the final state. The data, corresponding to an integrated luminosity of 2 fb −1, are collected by the ...

The production of χb(1P ) mesons in pp collisions at a centre-of-mass energy of 7 TeV is studied using 32 pb−1 of data collected with the LHCb detector. The χb(1P ) mesons are reconstructed in the decay ...
Measurement of sigma(pp -> b anti-b X) at sqrt(s)=7 TeV in the forward region
(Elsevier, 2010)
Decays of b hadrons into final states containing a Dº meson and a muon are used to measure the bb production cross-section in proton–proton collisions at a centre-of-mass energy of 7 TeV at the LHC. In ...
