Measurement of the ratio of B+c branching fractions to J/ψπ+ and J/ψμ+νμ final states
(American Physical Society, 2014-08-27)
The first measurement that relates semileptonic and hadronic decay rates of the B+c meson is performed using proton-proton collision data corresponding to 1.0 fb−1 of integrated luminosity collected ...
Measurement of the fragmentation fraction ratio f s /f d and its dependence on B meson kinematics
(Springer, 2013-04-02)
The relative production rate of B0s and B 0 mesons is determined with the hadronic decays B0s→D−sπ+ and B 0 → D − K +. The measurement uses data corresponding to 1.0 fb−1 of pp collisions at a centre-of-mass ...
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 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 ...
Production of J/ψ and Υ mesons in pp collisions at s√=8 TeV
(Springer, 2013-06-14)
The production of J/ψ and Υ mesons in pp collisions at s√=8 TeV is studied with the LHCb detector. The J/ψ and Υ mesons are reconstructed in the μ + μ − decay mode and the signal yields are determined ...
Precision measurement of D meson mass differences
(Springer, 2013-06-17)
Using three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D 0 mass. The ...
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 ...
Study of η − η′ mixing from measurement of B 0(s) → J/ψη(′) decay rates
(Springer, 2015-01-08)
A study of B and Bs meson decays into J/ψ η and J/ψ η′ final states is performed using a data set of proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, collected by the LCHb experiment ...
Study of forward Z + jet production in pp collisions at s√ = 7 TeV
(Springer, 2014-01-09)
A measurement of the Z(→ μ + μ −) + jet production cross-section in pp collisions at a centre-of-mass energy s√ = 7 TeV is presented. The analysis is based on an integrated luminosity of 1.0 fb−1 recorded ...
Determination of γ and −2βs from charmless two-body decays of beauty mesons
(Elsevier, 2015-02-04)
Using the latest LHCb measurements of time-dependent CP violation in the B-s(0) -> K+K- decay, a U-spin relation between the decay amplitudes of B-s(0) -> K+K- and B-0 -> p(+)p(-) decay processes allows ...
