First observations of the rare decays B + → K + π + π − μ + μ − and B +→ ϕK + μ + μ −
(Springer, 2014)
First observations of the rare decays B + → K + π + π − μ + μ − and B +→ ϕK +μ+μ− are presented using data corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment at centre-of-mass energies ...
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 ...

(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 ...
Measurement of the forward W boson cross-section in pp collisions at √s=7 TeV
(Springer, 2014)
A measurement of the inclusive W → μν production cross-section using data from pp collisions at a centre-of-mass energy of √s=7 TeV is presented. The analysis is based on an integrated luminosity of about 1.0 fb−1 recorded ...
Measurement of the CKM angle γ using B ± → DK ± with D → K0S π + π −, K0S K + K − decays
