Measurement of CP asymmetry in B0s → D ∓s K± decays
(Springer, 2014)
We report on measurements of the time-dependent CP violating observables in B 0s → D ∓s K ± decays using a dataset corresponding to 1.0 fb−1 of pp collisions recorded with the LHCb detector. We find the CP violating ...
Measurement of CP asymmetries and polarisation fractions in B0s→K∗0K¯∗0 decays
(Springer, 2015)
An angular analysis of the decay B0s→K∗0K¯∗0 is performed using pp collisions corresponding to an integrated luminosity of 1.0 fb−1 collected by the LHCb experiment at a centre-of-mass energy s√=7 TeV. A combined angular ...
Measurement of CP asymmetries in the decays B 0 → K *0 μ + μ − and B + → K + μ + μ −
(Springer, 2014)
The direct CP asymmetries of the decays B 0 → K *0 μ + μ − and B + → K + μ + μ − are measured using pp collision data corresponding to an integrated luminosity of 3.0 fb−1 collected with the LHCb detector. The respective ...
Measurements of the B +, B 0, B0s meson and Λ0b baryon lifetimes
(Springer, 2014)
Measurements of b-hadron lifetimes are reported using pp collision data, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb detector at a centre-of-mass energy of 7 TeV. Using the exclusive decays ...
Measurement of the CKM angle γ using B ± → DK ± with D → K0S π + π −, K0S K + K − decays

Measurement of polarization amplitudes and CP asymmetries in B 0 → ϕK*(892)0
(Springer, 2014)
An angular analysis of the decay B 0 → ϕK *(892)0 is reported based on a pp collision data sample, corresponding to an integrated luminosity of 1.0 fb−1, collected at a centre-of-mass energy of s√ = 7 TeV with the LHCb ...
Measurement of the B± production cross-section in pp collisions at √s=7 and 13 TeV
(Springer, 2017)
The production of B± mesons is studied in pp collisions at centre-of-mass energies of 7 and 13 TeV, using B± → J/ψ K± decays and data samples corresponding to 1.0 fb−1 and 0.3 fb−1, respectively. The production cross-sections ...
Resonances and CP violation in B0s and B¯0s→J/ψK+K− decays in the mass region above the ϕ(1020)
(Springer, 2017)
The decays of B 0s and B¯0s mesons into the J/ψK + K − final state are studied in the K + K − mass region above the ϕ(1020) meson in order to determine the resonant substructure and measure the CP-violating phase, ϕ s , ...
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 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 ...
