We report a study of the modes B± → DK ± and B± → DK± where D() decays to CP eigenstates. The data sample used contains 275 × 106 BB̄ events at the Y(4S) resonance collected by the Belle detector at the KEKB energy-asymmetric e+e- collider. The CP asymme ...
We have searched for the lepton flavor violating decays τ- → ℓ- KS 0 (ℓ = e or μ), using a data sample of 281 fb-1 collected with the Belle detector at the KEKB e+ e- asymmetric-energy collider. No evidence for a signal was found in either of the decay mod ...
Doubly-charged Higgs bosons are searched for in e+e- collision data collected with the L3 detector at LEP at centre-of-mass energies up to 209 GeV. Final states with four leptons are analysed to tag the pair-production of doubly-charged Higgs bosons. No si ...
The LHCb experiment is one of the main experiments that will be hosted at the Large Hadron Collider (LHC) at CERN, in the area of Geneva, and is scheduled to start after the Summer 2007. The LHCb detector is a single-arm forward spectrometer dedicated to p ...
The reported anomaly in deep-inelastic scattering at HERA has revived interest in the phenomenology of R-parity violation. From the theoretical point of view, the existence of R-violating interactions poses two considerable problems. The first one concerns ...
The LHCb experiment is one of the four large particle detectors currently under construction at the LHC accelerator at CERN. It is a forward single-arm spectrometer dedicated to precision measurements of CP violation and rare decays in the b quark sector. ...
We have searched for τ lepton decays, τ-→Λ̄π- and τ-→Λπ-, that simultaneously violate the conservation of the lepton (L) and baryon (B) number using a data sample of 154 fb-1 collected with the Belle detector at the KEKB e+e- asymmetric-energy collider. No ...
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 ...
