Tagged time-dependent angular analysis of B0s→J/ψϕ decays with the 2010 LHCb data
(13th International Conference on B-Physics at Hadron Machines, Amsterdam, 4-8 of April 2011, 2011-04)
The interference between B0s decays to Jψϕ either directly or via B0s−B¯0s oscillation gives rise to a CP violating phase ϕJ/ψϕs. In the Standard Model, this phase is approximately -2βs, where βs = arg ...
Optimization and calibration of the same-side kaon tagging algorithm using hadronic B0s decays in 2011 data
(Hadron Collider Physics Symposium, Kyoto, 12-16 of November 2012, 2012-11)
We report on the optimization and calibration of the same-side kaon tagging algorithm using the decay B0s→D−π+s with 1.0~fb−1 of data from the LHCb 2011 physics run. After a data-driven optimization and ...
Tagged time-dependent angular analysis of Bs→J/ψϕ decays with 337~pb−1 at LHCb
(25th International Symposium on Lepton Photon Interactions at High Energies, Mumbai, 22-27 of August 2011, 2011-08)
The interference between Bs decays to J/ψϕ either directly or via Bs−B¯¯¯¯s oscillation gives rise to a CP violating phase ϕJψϕs. Using a sample of 8276±94 Bs→J/ψϕ events extracted from 337~pb−1 of pp ...
Time Alignment and Calibration of the LHCb Calorimeter
(LHCb Conference Proceedings, Geneva, 2010, 2010)
Measurement of the ratio of branching fractions B(Bd→K∗0γ)/B(Bs→ϕγ) with the LHCb experiment at s√=7~TeV
(25th International Symposium on Lepton Photon Interactions at High Energies, Mumbai, 22-27 of August 2011, 2011-08)
The ratio of branching ratios of the radiative B decays Bd→K∗0γ and Bs→ϕγ has been measured using 340.1~pb−1 of \emph{pp} collisions at a centre of mass energy of s√=7~TeV taken with the LHCb detector. ...
Flavour Tagging at LHCb
(Physics at LHC, Vancouver, 4-9 of June 2012, 2012-06)
The identification of the flavour of reconstructed Bd and Bs mesons at production is necessary for the measurements of oscillations and time-dependent CP asymmetries. The calibration and performance of ...
