First Measurement of the CP-Violating Phase in B0s→ϕϕ Decays
(American Physical Society, 2013-06-12)
A first flavor-tagged measurement of the time-dependent CP-violating asymmetry in B0s→ϕϕ decays is presented. In this decay channel, the CP-violating weak phase arises due to CP violation in the ...
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 effective B0s → K+K- lifetime
(Elsevier, 2012-10-02)
A precise determination of the effectiveB0s→K+K−lifetime can be used to con-strain contributions from physics beyond the Standard Model in theB0smesonsystem. Conventional approaches selectBmeson ...
Measurement of the cross-section for Z → e+e- production in pp collisions at s√=7 TeV
(Springer, 2013-02-19)
A measurement of the cross-section for pp → Z → e+e− is presented using data at s√=7
TeV corresponding to an integrated luminosity of 0.94 fb−1. The process is measured within the kinematic acceptance ...
Observation of charmonium pairs produced exclusively in pp collisions
(IOPscience, 2014-09)
A search is performed for the central exclusive production of pairs of charmonia produced in proton-proton collisions. Using data corresponding to an
integrated luminosity of 3 fb−1 collected at ...
Measurement of the time-dependent CP asymmetries in B 0s → J/ψK 0S

Measurement of the B 0 → K ∗0 e + e − branching fraction at low dilepton mass
(Springer, 2013-05-29)
The branching fraction of the rare decay B 0 → K ∗0 e + e − in the dilepton mass region from 30 to 1000 MeV/c 2 has been measured by the LHCb experiment, using pp collision data, corresponding to an ...
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 ...
Study of B− → DK−π+π− and B− → Dπ−π+π− decays and determination of the CKM angle γ
(American Physical Society, 2015-12-17)
We report a study of the suppressed B−→DK−π+π− and favored B−→Dπ−π+π− decays, where the neutral D meson is detected through its decays to the K∓π± and CP -even K+K− and π+π− final states. The measurement ...
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 ...
