Angular analysis and differential branching fraction of the decay B 0s → ϕμ + μ −
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 ...
Measurement of the forward-backward asymmetry in Z/γ∗ → μ + μ − decays and determination of the effective weak mixing angle
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
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 ...
Measurement of the B 0s → ϕϕ branching fraction and search for the decay B 0 → ϕϕ
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 ...
Evidence for the decay B+c→J/ψ3π+2π−
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 ...
