A study of the Z production cross-section in pp collisions at s√=7TeV using tau final states
(Springer, 2013-01-16)
A measurement of the inclusive Z → ττ cross-section in pp collisions at s√=7TeV is presented based on a dataset of 1.0 fb−1 collected by the LHCb detector. Candidates for Z → τ τ decays are identified ...
Measurement of J/ψ production in pp collisions at s√=2.76TeV
(Springer, 2013-02-07)
The production of J/ψ mesons is studied with the LHCb detector using data from pp collisions at s√=2.76 TeV corresponding to an integrated luminosity of 71 nb−1. The differential cross-section for ...
Model-independent confirmation of the Z(4430)− state
(American Physical Society, 2015-12-29)
The decay B0→ψ(2S)K+π− is analyzed using 3 fb−1 of pp collision data collected with the LHCb detector. A model-independent description of the ψ(2S)π mass spectrum is obtained, using as input the Kπ ...
Measurement of the ¯B0s→D−sD+s and ¯B0s→D−D+s Effective Lifetimes
(American Physical Society, 2014-03-19)
The first measurement of the effective lifetime of the ¯B0s meson in the decay ¯B0s→D−sD+s is reported using a proton-proton collision data set, corresponding to an integrated luminosity of 3 fb−1, ...
Observation of the B0s → D*±D∓ decay
(Springer, 2021-03)
A search for the B0s
→ D*±D∓ decay is performed using proton-proton collision data at centre-of-mass energies of 7, 8 and 13 TeV collected by the LHCb experiment, corresponding to an integrated luminosity ...
Measurement of the Λ0b, Ξ−b, and Ω−b Baryon Masses
(American Physical Society, 2013-05-02)
Bottom baryons decaying to a J/ψ meson and a hyperon are reconstructed using 1.0 fb−1 of data collected in 2011 with the LHCb detector. Significant Λ0b→J/ψΛ, Ξ−b→J/ψΞ− and Ω−b→J/ψΩ− signals are observed ...
Effective lifetime measurements in the B0s → K+K− , B0 → K+π− and B0s → π+K− decays
(Elsevier, 2014-09-07)
Measurements of the effective lifetimes in the B0s→K+K−, B0→K+π− and B0s→π+K− decays are presented using 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. ...
Measurement of CP violation parameters and polarisation fractions in B0s→J/ψK¯¯¯¯∗0 decays
(Springer, 2015-11-12)
The first measurement of CP asymmetries in the decay B0s→J/ψK¯¯¯¯∗(892)0 and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using ...
Observation of D0−¯¯¯D0 Oscillations
(American Physical Society, 2013-03-05)
We report a measurement of the time-dependent ratio of D0→K+π− to D0→K−π+ decay rates in D*+-tagged events using 1.0 fb−1 of integrated luminosity recorded by the LHCb experiment. We measure the mixing ...
Measurements of the branching fractions of the decays B0s→D∓sK± and B0s→D−sπ+
(Springer, 2012-06-20)
The decay mode B0s→D∓sK± allows for one of the theoretically cleanest measurements of the CKM angle γ through the study of time-dependent CP violation. This paper reports a measurement of its branching ...
