First observation of B0 → D∗+ Xμ−ν decays
(Elsevier, 2011)
Using data collected with the LHCb detector in proton-proton collisions at a centre-of-mass energy of 7 TeV, the semileptonic decays Bs -> Ds+ X mu nu and Bs -> D0 K+ X mu nu are detected. Two structures ...
Determination of fs/fd for 7 TeV pp Collisions and Measurement of the B0→D−K+ Branching Fraction
(American Physical Society, 2011-11-14)
The relative abundance of the three decay modes B0→D−K+, B0→D−π+, and B0s→D−sπ+ produced in 7 TeV pp collisions at the LHC is determined from data corresponding to an integrated luminosity of 35 pb−1. ...
First observation of B0s → J/ψ f0(980) decays
(Elsevier, 2011-01)
Using data collected with the LHCb detector in proton-proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decayB0s→J/ψf0(980) is observed. ThisCP eigenstate mode could be used to measure ...
