Study of the D0 p amplitude in Λ0b → D0 pπ − decays
(Springer, 2017)
An amplitude analysis of the decay Λ0b → D0 pπ − is performed in the part of the phase space containing resonances in the D0 p channel. The study is based on a data sample corresponding to an integrated luminosity of 3.0 ...
Updated branching fraction measurements of B0(s) → K0Sh+h′ − decays
(Springer, 2017)
The charmless three-body decays B 0( s) → K0Sh+h′ − (where h(′) = π, K) are analysed using a sample of pp collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 3 fb−1. The branching ...
Observation of the decay Λ0b → pK − μ + μ − and a search for CP violation
(Springer, 2017)
A search for CP violation in the decay Λ0b → pK − μ + μ − is presented. This decay is mediated by flavour-changing neutral-current transitions in the Standard Model and is potentially sensitive to new sources of CP violation. ...
Measurement of the J/ψ pair production cross-section in pp collisions at √s=13 TeV
(Springer, 2017)
The production cross-section of J/ψ pairs is measured using a data sample of pp collisions collected by the LHCb experiment at a centre-of-mass energy of √s=13 TeV, corresponding to an integrated luminosity of 279 ±11 pb−1. ...
Measurement of forward top pair production in the dilepton channel in pp collisions at √s=13 TeV
(Springer, 2018)
Forward top quark pair production is studied in pp collisions in the μeb final state using a data sample corresponding to an integrated luminosity of 1.93 fb−1 collected with the LHCb experiment at a centre-of-mass energy ...
Observation of the decay Λ 0b → ψ(2S)pπ−
(Springer, 2018)
The Cabibbo-suppressed decay Λ 0b → ψ(2S)pπ− is observed for the first time using a data sample collected by the LHCb experiment in proton-proton collisions corresponding to 1.0, 2.0 and 1.9 fb−1 of integrated luminosity ...
Measurement of the CKM angle γ using B± → DK± with D → K0Sπ+π−, K0SK+K− decays
(Springer, 2018)
A binned Dalitz plot analysis of B± → DK± decays, with D → K 0Sπ+π− and D → K 0SK+K−, is used to perform a measurement of the CP-violating observables x± and y±, which are sensitive to the Cabibbo-Kobayashi-Maskawa angle ...
Measurement of Z → τ +τ − production in proton-proton collisions at √s=8 TeV
(Springer, 2018)
A measurement of Z → τ +τ − production cross-section is presented using data, corresponding to an integrated luminosity of 2 fb−1, from pp collisions at √s=8 TeV collected by the LHCb experiment. The τ +τ − candidates are ...
Observation of the decay B¯0s→χc2K+K− in the ϕ mass region
(Springer, 2018)
The B¯0s→χc2K+K− decay mode is observed and its branching fraction relative to the corresponding χc1 decay mode, in a ±15 MeV/c2 window around the ϕ mass, is found to be
B(B¯0s→χc2K+K−)B(B¯0s→χc1K+K−)=(17.1±3.1±0.4±0. ...
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 ...
