Measurement of the Z+b-jet cross-section in pp collisions at √s = 7 TeV in the forward region
(Springer, 2015)
The associated production of a Z boson or an off-shell photon γ * with a bottom quark in the forward region is studied using proton-proton collisions at a centre-of-mass energy of 7 TeV. The Z bosons are reconstructed in ...
Measurement of forward Z → e+e− production s√s=8 TeV
(Springer, 2015)
A measurement of the cross-section for Z-boson production in the forward region of pp collisions at 8 TeV centre-of-mass energy is presented. The measurement is based on a sample of Z → e+e− decays reconstructed using the ...
Measurement of the exclusive Υ production cross-section in pp collisions at √s=7 TeV and 8 TeV
(Springer, 2015)
A study is presented of central exclusive production of Υ(nS) states, where the Υ(nS) resonances decay to the μ + μ − final state, using pp collision data recorded by the LHCb experiment. The cross-section is measured in ...
Measurement of indirect CP asymmetries in D0 → K−K+ and D0 → π−π+ decays using semileptonic B decays
(Springer, 2015)
Time-dependent CP asymmetries in the decay rates of the singly Cabibbo-suppressed decays D0 → K−K+ and D0 → π−π+ are measured in pp collision data corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb ...
Precise measurements of the properties of the B1(5721)0,+ and B *2(5747)0,+ states and observation of B+,0π−,+ mass structures
(Springer, 2015)
Invariant mass distributions of B+π− and B0π+ combinations are investigated in order to study excited B mesons. The analysis is based on a data sample corresponding to 3.0 fb−1 of pp collision data, recorded by the LHCb ...
Measurement of the forward Z boson production cross-section in pp collisions at √s =7 TeV
(Springer, 2015)
A measurement of the production cross-section for Z bosons that decay to muons is presented. The data were recorded by the LHCb detector during pp collisions at a centre-of-mass energy of 7 TeV, and correspond to an ...
Measurement of the inelastic pp cross-section at a centre-of-mass energy of √s = 7 TeV
(Springer, 2015)
The cross-section for inelastic proton-proton collisions, with at least one prompt long-lived charged particle of transverse momentum p T > 0.2GeV/c in the pseudorapidity range 2.0 < η < 4.5, is measured by the LHCb ...
Search for the decay B0s→D¯0f0 (980)
(Springer, 2015)
A search for B0s→D¯0f0(980) decays is performed using 3.0 fb1− of pp collision data recorded by the LHCb experiment during 2011 and 2012. The f0(980) meson is reconstructed through its decay to the π+π− final state in the ...
Measurement of the time-dependent CP asymmetries in B0s → J/ψK0S
(Springer, 2015)
The first measurement of decay-time-dependent CP asymmetries in the decay B0s → J/ψK0S and an updated measurement of the ratio of branching fractions B(B0s→J/ψK0S)/B(B0→J/ψK0S)are presented. The results are obtained using ...
Search for the lepton flavour violating decay τ − → μ − μ + μ −
(Springer, 2015)
A search for the lepton flavour violating decay τ − → μ − μ + μ − is performed with the LHCb experiment. The data sample corresponds to an integrated luminosity of 1.0 fb−1 of proton-proton collisions at a centre-of-mass ...
