Measurement of ϒ production in pp collisions at √ s = 2.76 TeV
(Springer, 2014-04-29)
The production of Υ(1S), Υ(2S) and Υ(3S) mesons decaying into the dimuon final state is studied with the LHCb detector using a data sample corresponding to an integrated luminosity of 3.3pb−1 collected ...
First observation of B0 → D∗+ Xμ−ν decays
(Elsevier, 2011)
Using data collected with the LHCb detector in proton-proton collisions at a centre-of-mass energy of 7 TeV, the semileptonic decays Bs -> Ds+ X mu nu and Bs -> D0 K+ X mu nu are detected. Two structures ...
Measurement of the cross-section ratio σ(χc2)/σ(χc1) for prompt χc production at √s=7TeV
(Elsevier, 2012-08-14)
The prompt production of the charmonium $\chi_{c1}$ and $\chi_{c2}$ mesons has been studied in proton-proton collisions at the Large Hadron Collider at a centre-of-mass energy of $\sqrt{s}=7$ TeV. The ...
Measurement of D0–¯¯¯D0 Mixing Parameters and Search for CP Violation Using D0→K+π− Decays
(American Physical Society, 2013-12-18)
Measurements of charm mixing parameters from the decay-time-dependent ratio of D0→K+π− to D0→K−π+ rates and the charge-conjugate ratio are reported. The analysis uses data, corresponding to 3 fb−1 of ...
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 ...
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 ...
Measurement of ψ(2S) polarisation in pp collisions at s√ = 7 TeV
(Springer, 2014-05-20)
The polarisation of prompt ψ(2S) mesons is measured by performing an angular analysis of ψ(2S)→μ+μ− decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb −1, ...
