We report measurements of B meson decays to two kaons using 253fb-1 of data collected with the Belle detector at the KEKB energy-asymmetric e+e- collider. We find evidence for signals in B+→K̄0K+ and B0→K0K̄0 with significances of 3.0σ and 3.5σ, respective ...
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 ...
The CP asymmetry parameters in the decay B0(B̄0) → J/ψπ0, were described. The measurement of the CP asymmetry parameters was based on a 140 fb-1 data sample, which was accumulated at the γ(4S) resonance by the Belle detector at the KEKB asymmetric-energy e ...
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 ...
We have searched for neutrinoless τ lepton decays into ℓhh or ℓ V0, where ℓ stands for an electron or muon, h for a charged light hadron, π or K, and V0 for a neutral vector meson, ρ0, K* (892)0 and φ{symbol}, using a 158 fb-1 data sample collected with th ...
