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 ...
A search for charged and neutral excited leptons is performed in 217 pb(-1) of e(+)e(-) collision data collected with the L3 detector at LEP at centre-of-mass energies from 202 up to 209 GeV The pair- and single-production mechanisms of excited electrons, ...
We have searched for neutrinoless τ lepton decays into three charged leptons using an 87.1fb-1 data sample collected with the Belle detector at the KEKB e+e- collider. Since the number of signal candidate events is compatible with that expected from the ba ...
The QED processes e+e-→e+e -μ+μ- and e+e -→e+e-τ+τ- are studied with the L3 detector at LEP using an untagged data sample collected at centre-of-mass energies 161 GeV≤√s≤209 GeV. The τ-pairs are observed through the associated decay of one τ into eνν and t ...
We have searched for a CP violation signature arising from an electric dipole moment (dτ) of the τ lepton in the e+e- → τ+τ- reaction. Using an optimal observable method and 29.5 fb-1 of data collected with the Belle detector at the KEKB collider at √s= 10 ...
