Measurement of CP observables in B± → DK*± decays using two- and four-body D final states
(Springer, 2017)
Measurements of CP observables in B± → DK*± decays are presented, where D denotes a superposition of D0 and D¯0 meson states. Decays of the D meson to K−π+, K−K+, π−π+, K−π+π−π+ and π−π+π−π+ are used and the K*± meson is ...
Measurement of the flavour-specific CP-violating asymmetry assl in B0s decays
(Elsevier, 2014)
The CP-violating asymmetry as
sl is studied using semileptonic decays of B0s
and B0s
mesons produced in
pp collisions at a centre-of-mass energy of 7 TeV at the LHC, exploiting a data sample corresponding
to an ...
Measurement of CP violation in B0 → J/ψK 0S and B0 → ψ(2S)K0S decays
(Springer, 2017)
A measurement is presented of decay-time-dependent CP violation in the decays B0 → J/ψ K 0S and B0 → ψ(2S)K 0S, where the J/ψ is reconstructed from two electrons and the ψ(2S) from two muons. The analysis uses a sample of ...
Observation of the decay B0s → η c ϕ and evidence for B 0s → η c π + π −
(Springer, 2017)
A study of B0s → η c ϕ and B0s → η c π + π − decays is performed using pp collision data corresponding to an integrated luminosity of 3.0 fb−1, collected with the LHCb detector in Run 1 of the LHC. The observation of the ...
Test of lepton universality with B0 → K *0 ℓ + ℓ − decays
(Springer, 2017)
A test of lepton universality, performed by measuring the ratio of the branching fractions of the B 0 → K *0 μ + μ − and B 0 → K *0 e + e − decays, RK∗0, is presented. The K *0 meson is reconstructed in the final state K ...
Study of prompt D0 meson production in pPb collisions at √sNN=5 TeV
(Springer, 2017)
Production of prompt D0 mesons is studied in proton-lead and lead-proton collisions recorded at the LHCb detector at the LHC. The data sample corresponds to an integrated luminosity of 1.58±0.02 nb−1 recorded at a ...
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. ...
Search for CP violation in D± → K 0S K ± and D±s → K 0S π ± decays
(Springer, 2014)
A search for CP violation in Cabibbo-suppressed D ± → K 0S K ± and D ±s → K 0S π ± decays is performed using pp collision data, corresponding to an integrated luminosity of 3 fb, recorded by the LHCb experiment. The ...
