Angular analysis and differential branching fraction of the decay B 0s → ϕμ + μ −
(Springer, 2015)An angular analysis and a measurement of the differential branching fraction of the decay B 0s → ϕμ + μ − are presented, using data corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions recorded by the ... -
Coherent ρ 0 photoproduction in ultra-peripheral Pb-Pb collisions at √sNN=2.76 TeV
(Springer, 2015)We report the first measurement at the LHC of coherent photoproduction of ρ 0 mesons in ultra-peripheral Pb-Pb collisions. The invariant mass and transverse momentum distributions for ρ 0 production are studied in the ... -
Evidence for the decay B+c→J/ψ3π+2π−
(Springer, 2014)Evidence is presented for the decay B + c → J/ψ3π +2π − using proton-proton collision data, corresponding to an integrated luminosity of 3 fb−1 , collected with the LHCb detector. A signal yield of 32 ± 8 decays is ... -
Forward-backward multiplicity correlations in pp collisions at √s = 0.9, 2.76 and 7 TeV
(Springer, 2015)The strength of forward-backward (FB) multiplicity correlations is measured by the ALICE detector in proton-proton (pp) collisions at √s= 0.9, 2.76 and 7 TeV. The measurement is performed in the central pseudorapidity ... -
Inclusive, prompt and non-prompt J/ψ production at mid-rapidity in Pb-Pb collisions at √sNN = 2.76 TeV
(Springer, 2015)The transverse momentum (pT) dependence of the nuclear modification factor RAA and the centrality dependence of the average transverse momentum 〈pT〉 for inclusive J/ψ have been measured with ALICE for Pb-Pb collisions at ... -
Measurement of charm and beauty production at central rapidity versus charged-particle multiplicity in proton-proton collisions at √s=7 TeV
(Springer, 2015)Prompt D meson and non-prompt J/ψ yields are studied as a function of the multiplicity of charged particles produced in inelastic proton-proton collisions at a centre-of-mass energy of √s=7 TeV. The results are reported ... -
Measurement of the B 0s → ϕϕ branching fraction and search for the decay B 0 → ϕϕ
(Springer, 2015)Using a dataset corresponding to an integrated luminosity of 3.0 fb−1 collected in pp collisions at centre-of-mass energies of 7 and 8 TeV, the B 0s → ϕϕ branching fraction is measured to be B(B0s→ϕϕ)=(1.84±0.05(stat ... -
Measurement of the forward-backward asymmetry in Z/γ∗ → μ + μ − decays and determination of the effective weak mixing angle
(Springer, 2015)The forward-backward charge asymmetry for the process qq→Z/γ∗→μ+μ− is measured as a function of the invariant mass of the dimuon system. Measurements are performed using proton proton collision data collected with the LHCb ... -
Observation of associated production of a Z boson with a D meson in the forward region
(Springer, 2014)A search for associated production of a Z boson with an open charm meson is presented using a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of proton-proton collisions at a centre-of-mass energy of ...
