Evidence for the Strangeness-Changing Weak Decay Ξ−b→Λ0bπ−
(American Physical Society, 2015-12-11)
Using a pp collision data sample corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb detector, we present the first search for the strangeness-changing weak decay Ξ−b→Λ0bπ−. ...
First Observation of Top Quark Production in the Forward Region
(American Physical Society, 2015-09-08)
Top quark production in the forward region in proton-proton collisions is observed for the first time. The W+b final state with W→μν is reconstructed using muons with a transverse momentum, pT, larger ...
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. ...
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 ...
Measurement of B+c Production in Proton-Proton Collisions at √s=8 TeV
(American Physical Society, 2015-04-02)
Production of B+c mesons in proton-proton collisions at a center-of-mass energy of 8 TeV is studied with data corresponding to an integrated luminosity of 2.0 fb−1 recorded by the LHCb experiment. The ...
Measurement of the Ratio of Branching Fractions B(¯B0→D*+τ−¯ντ)/B(¯B0→D*+μ−¯νμ)
(American Physical Society, 2015-09-09)
The branching fraction ratio R(D∗)≡B(¯B0→D*+τ−¯ντ)/B(¯B0→D*+μ−¯νμ) is measured using a sample of proton-proton collision data corresponding to 3.0 fb−1 of integrated luminosity recorded by the LHCb ...
