Evidence for the decay B0S→K¯∗0μ+μ−
(Springer, 2018)
A search for the decay B0S→K¯∗0μ+μ− is presented using data sets corresponding to 1.0, 2.0 and 1.6 fb−1 of integrated luminosity collected during pp collisions with the LHCb experiment at centre-of-mass energies of 7, 8 ...
Measurement of D ±s production asymmetry in pp collisions at √s=7 and 8 TeV
(Springer, 2018)
The inclusive D ±s production asymmetry is measured in pp collisions collected by the LHCb experiment at centre-of-mass energies of √s=7 and 8 TeV. Promptly produced D ±s mesons are used, which decay as D ±s → ϕπ±, with ...
Search for CP violation using triple product asymmetries in Λ 0b → pK−π+π−, Λ 0b → pK−K+K− and Ξ 0b → pK−K−π+ decays
(Springer, 2018)
A search for CP and P violation using triple-product asymmetries is performed with Λ 0b → pK−π+π−, Λ 0b → pK−K+K− and Ξ 0b → pK−K−π+ decays. The data sample corresponds to integrated luminosities of 1.0 fb−1 and 2.0 fb−1, ...
Measurement of ϒ production in pp collisions at √s=13 TeV
(Springer, 2018)
The production cross-sections of ϒ(1S), ϒ(2S) and ϒ(3S) mesons in proton-proton collisions at √s=13 TeV are measured with a data sample corresponding to an integrated luminosity of 277 ± 11 pb−1 recorded by the LHCb ...
Measurement of the time-integrated CP asymmetry in D0 → K0SK0S decays
(Springer, 2018)
A measurement of the time-integrated CP asymmetry in D0 → K0SK0S decays is reported. The data correspond to an integrated luminosity of about 2 fb−1 collected in 2015–2016 by the LHCb collaboration in pp collisions at a ...
Search for beautiful tetraquarks in the ϒ(1S)μ+μ− invariant-mass spectrum
(Springer, 2018)
The ϒ(1S)μ+μ− invariant-mass distribution is investigated for a possible exotic meson state composed of two b quarks and two b¯ quarks, Xbb¯bb¯. The analysis is based on a data sample of pp collisions recorded with the ...
Central exclusive production of J/ψ and ψ(2S) mesons in pp collisions at √s=13 TeV
(Springer, 2018)
Measurements are reported of the central exclusive production of J/ψ and ψ(2S) mesons in pp collisions at a centre-of-mass energy of 13 TeV. Backgrounds are significantly reduced compared to previous measurements made at ...
Angular moments of the decay Λ0b → Λμ+μ− at low hadronic recoil
(Springer, 2018)
An analysis of the angular distribution of the decay Λ0b → Λμ+μ− is presented, using data collected with the LHCb detector between 2011 and 2016 and corresponding to an integrated luminosity of approximately 5 fb−1. Angular ...
Search for a dimuon resonance in the ϒ mass region
(Springer, 2018)
A search is performed for a spin-0 boson, ϕ, produced in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, using prompt ϕ → μ+μ− decays and a data sample corresponding to an integrated luminosity of ...
Measurement of Z → τ +τ − production in proton-proton collisions at √s=8 TeV
