Observation of the Λ 0 b → J/ψ pπ − decay
(Springer, 2014-07-22)
The first observation of the Cabibbo-suppressed decay Λ 0 b → J/ψpπ − is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. A ...
Evidence for the decay X(3872) →ψ(2S)γ
(Elsevier, 2014-09)
Evidence for the decay mode X(3872) →ψ(2S)γ in B+→X(3872)K+decays is found with a sig-nificance of 4.4 standard deviations. The analysis is based on a data sample of proton–proton collisions, corresponding ...
Precision Measurement of the Mass and Lifetime of the Ξ0b Baryon
(American Physical Society, 2014-07-15)
Using a proton-proton collision data sample corresponding to an integrated luminosity of 3 fb−1 collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 Ξ0b→Ξ+cπ−, Ξ+c→pK−π+ signal decays ...
Exclusive J/ψ and ψ(2S) production in pp collisions at √s= 7 TeV
(IOPscience, 2013-02)
Exclusive J/ψ and ψ(2S) vector meson production has been observed in the
dimuon channel using the LHCb detector. The cross-section times branching
fractions to two muons with pseudorapidities between ...
Measurement of the relative rate of prompt χ c0, χ c1 and χ c2 production at s√=7 TeV
(Springer, 2013-10-18)
Prompt production of charmonium χ c0, χ c1 and χ c2 mesons is studied using proton-proton collisions at the LHC at a centre-of-mass energy of s√=7 TeV. The χ c mesons are identified through their decay ...

(Springer, 2014-08-19)
The first observation of Z boson production in proton-lead collisions at a centre-of-mass energy per proton-nucleon pair of sNN−−−−√
= 5 TeV is presented. The data sample corresponds to an integrated ...
Studies of the decays B+→p¯ph+ and observation of B+→¯¯¯Λ(1520)p
(American Physical Society, 2013-09-19)
Dynamics and direct CP violation in three-body charmless decays of charged B mesons to a proton, an antiproton and a light meson (pion or kaon) are studied using data, corresponding to an integrated ...
First observation and measurement of the branching fraction for the decay B 0 s → D ∗ s ∓ K ±
(Springer, 2015-06-18)
The first observation of the B 0 s → D ∗ s ∓ K ± decay is reported using 3.0 fb−1 of proton-proton collision data collected by the LHCb experiment. The D ∗ s ∓ mesons are reconstructed through the decay ...
Study of Beauty Hadron Decays into Pairs of Charm Hadrons
(American Physical Society, 2014-05-21)
First observations of the decays Λ0b→Λ+cD−(s) are reported using data corresponding to an integrated luminosity of 3 fb−1 collected at 7 and 8 TeV center-of-mass energies in proton-proton collisions ...
Measurement of the CKM angle γ using B ± → DK ± with D → K 0 S π + π −, K 0 S K + K − decays
(Springer, 2014-10-16)
A binned Dalitz plot analysis of B ± → DK ± decays, with D→K0Sπ+π− and D→K0SK+K−, is performed to measure the CP-violating observables x ± and y ±, which are sensitive to the Cabibbo-Kobayashi-Maskawa ...
