Angular analysis of charged and neutral B → Kμ + μ − decays
(Springer, 2014)
The angular distributions of the rare decays B + → K + μ + μ − and B0→K0Sμ+μ− are studied with data corresponding to 3fb−1 of integrated luminosity, collected in proton-proton collisions at 7 and 8 TeV centre-of-mass ...
A study of CP violation in B± →DK± and B±→Dπ± decays with D→K0SK±π∓ final states
(Elsevier, 2014)
A first study of CP violation in the decay modes B±→[KS 0 K±π∓] D h±and B±→[KS 0 K∓ π±]
D h±, where h labels a K or π meson and D labels a D 0 or D‾ 0 meson, is performed. The
analysis uses the LHCb data set collected ...
Differential branching fractions and isospin asymmetries of B → K (*) μ + μ − decays
(Springer, 2014)
The isospin asymmetries of B → Kμ + μ − and B → K * μ + μ − decays and the partial branching fractions of the B 0 → K 0 μ + μ −, B + → K + μ + μ − and B + → K *+ μ + μ − decays are measured as functions of the dimuon mass ...
Effective lifetime measurements in the B0s→K+K−, B0→K+π−and B0s→π+K−decays
(Elsevier, 2014)
Measurements of the effective lifetimes in the B0s→K+K−, B0→K+π−and B0s→π+K−decays are presented using 1.0fb−1of ppcollision data collected at a centre-of-mass energy of 7TeV by the LHCb experiment. The analysis uses a ...

(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 ...
Evidence for the decay X(3872) →ψ(2S)γ
(Elsevier, 2014)
Evidence for the decay mode X(3872) →ψ(2S)γin B+→X(3872)K+decays is found with a sig-nificance of 4.4 standard deviations. The analysis is based on adata sample of proton–proton collisions, corresponding to an integrated ...
