Search for Hidden-Sector Bosons in B0→K*0μ+μ− Decays
(American Physical Society, 2015-10-16)
A search is presented for hidden-sector bosons, χ, produced in the decay B0→K∗(892)0χ, with K∗(892)0→K+π− and χ→μ+μ−. The search is performed using pp-collision data corresponding to 3.0 fb−1 collected ...
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 ...
First Observation of CP Violation in the Decays of B0s Mesons
(American Physical Society, 2013-05-30)
Using pp collision data corresponding to an integrated luminosity of 1.0 fb−1 and collected by LHCb in 2011 at a center-of-mass energy of 7 TeV, we report the measurement of direct CP violation in ...
Observation of B(s)(0) → J/ψf(2)'(1525) in J/ψK+ K- final states
(American Physical Society, 2012-04-09)
The decay ¯¯¯B0s→J/ψK+K− is investigated using 0.16 fb−1 of data collected with the LHCb detector using 7 TeV pp collisions. Although the J/ψϕ channel is well known, final states at higher K+K− masses ...

(Elsevier, 2015-07-30)
The decay B-0s → ψ(2S)K+π- is observed using a data set corresponding to an integrated luminosity of 3.0fb-1 collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. ...
Strong Constraints on the Rare Decays B0s→μ+μ− and B0→μ+μ−
(American Physical Society, 2012-06-05)
A search for B0s→μ+μ− and B0→μ+μ− decays is performed using 1.0 fb−1 of pp collision data collected at √s=7 TeV with the LHCb experiment at the Large Hadron Collider. For both decays, the number of ...
Measurement of the D± production asymmetry in 7 TeV pp collisions
(Elsevier, 2013-01-08)
The asymmetry in the production cross-section \sigma of D+/- mesons, A_P = (\sigma(D+) - \sigma(D-))/(\sigma(D+) + \sigma(D-)), is measured in bins of pseudorapidity \eta and transverse momentum p_T ...
First observation of B0s → J/ψ f0(980) decays
(Elsevier, 2011-01)
Using data collected with the LHCb detector in proton-proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decayB0s→J/ψf0(980) is observed. ThisCP eigenstate mode could be used to measure ...
First observation of the decay B0s→K∗0K∗0
(Elsevier, 2012-03-13)
The first observation of the decay $\kstarkstar$ is reported using 35\invpb of data collected by LHCb in proton-proton collisions at a centre-of-mass energy of 7 TeV. A total of $49.8 \pm 7.5$ $B^0_s ...
