First measurement of the differential branching fraction and CP asymmetry of the B ± → π ± μ + μ − decay
(Springer, 2015)
The differential branching fraction with respect to the dimuon invariant mass squared, and the CP asymmetry of the B ± → π ± μ + μ − decay are measured for the first time. The CKM matrix elements |V td | and |V ts |, and ...
Angular analysis of the B0 → K*0e+e− decay in the low-q2 region
(Springer, 2015)
An angular analysis of the B0 → K*0e+e− decay is performed using a data sample, corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and ...
Prompt and nonprompt J/ψ production and nuclear modification in pPb collisions at √sNN = 8.16 TeV

Measurement of forward W and Z boson production in association with jets in proton-proton collisions at √s=8 TeV
(Springer, 2016)
The production of W and Z bosons in association with jets is studied in the forward region of proton-proton collisions collected at a centre-of-mass energy of 8 TeV by the LHCb experiment, corresponding to an integrated ...
Model-independent measurement of the CKM angle γ using B0 → DK∗0 decays with D → K0S π + π − and K0SK+K−
(Springer, 2016)
A binned Dalitz plot analysis of the decays B 0 → DK ∗0, with D → K 0S π + π − and D → K 0S K + K −, is performed to measure the observables x ± and y ±, which are related to the CKM angle γ and the hadronic parameters ...
Measurement of the properties of the Ξ ∗ 0b baryon
(Springer, 2016)
We perform a search for near-threshold Ξ 0b resonances decaying to Ξ −b π + in a sample of proton-proton collision data corresponding to an integrated luminosity of 3 fb−1 collected by the LHCb experiment. We observe one ...
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
(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 ...
Forward production of Υ mesons in pp collisions at √s=7 and 8 TeV
(Springer, 2015)
The production of Υ mesons in pp collisions at √s=7 and 8 TeV is studied with the LHCb detector using data samples corresponding to an integrated luminosity of 1 fb−1 and 2 fb−1 respectively. The production cross-sections ...
