A BiCMOS discriminator interface for the SPD
(2000-09)A prototype chip for the analogue readout of the SPD in the LHCb Calorimeter is presented. The chip has been designed using the 0.8mm-BiCMOS technology of AMS and optimised for minimum size and ... -
Flavour Tagging at LHCb
(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 ... -
Measurement of the ratio of branching fractions B(Bd→K∗0γ)/B(Bs→ϕγ) with the LHCb experiment at s√=7~TeV
(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. ... -
Tagged time-dependent angular analysis of B0s→J/ψϕ decays with the 2010 LHCb data
(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 ... -
Tagged time-dependent angular analysis of Bs→J/ψϕ decays with 337~pb−1 at LHCb
(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 ... -
The Front End Electronics of the Scintillator Pad Detector of the LHCb Calorimeter
(Proceedings of the Twelfth Workshop on Electronics for LHC and Future Experiments, 2006-09)In this paper the Front End electronics of the Scintillator Pad Detector (SPD) is outlined. The SPD is a sub-system of the Calorimeter of the LHCb experiment designed to discriminate between charged and ...
