The LHCb experiment will be installed in the proton-proton Large Hadron Collider (LHC) at CERN, Geneva. The detector is a single arm spectrometer currently under construction: LHC running and LHCb data taking will start in 2007. LHCb will then benefit from ...
We report on a measurement of the branching fractions for B- → D()+π- ℓ -v̄ℓ and B̄0 → D ()0π+ℓ-v̄ℓ with 275 × 106 BB̄ events collected at the γ(4S) resonance with the Belle detector at KEKB. Events are tagged by fully reconstructing one of the B mesons ...
We report results of a study of charmless B meson decays to three-body Kππ, KKπ and KKK final states. Measurements of branching fractions for B decays to K=+(0)π+π-, K +K+K-, K0K+K-, K+Ks 0Ks 0 and K s 0Ks 0Ks 0 final states are presented. The decays B0→K0 ...
The observation of the hyperonic B+ → λλ̄K+ decay was presented. It was found that the rate of a charmless B decay was comparable to that of other charmless three-body baryonic modes. It was also found that the invariant mass of the λλ̄ system had a promin ...
