Leptonvector-lepton mixings and unitarity bounds

Physical Review D, 1988
Vector leptons (N,E) are present in both E/sub 6/ and SO(18) unified theories. We derive linear relations between the masses of these vector leptons and ordinary leptons, and their mixing angles. We calculate the amplitudes for such processes as E/sup +/E/sup -/..-->..E/sup +/E/sup -/ and e/sup +/E/sup -/..-->..boson-boson. We find that these relations

Decay-lepton distributions from photoproduced heavy leptons

Physical Review D, 1977
We discuss heavy-lepton pair production via the reaction $\ensuremath{\gamma}+Z\ensuremath{\rightarrow}{L}^{+}+{L}^{\ensuremath{-}}+Z$ followed by the decays ${L}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{\ifmmode\pm\else\textpm\fi{}}+\ensuremath{\nu}+\overline{\ensuremath{\nu}}$ or ${L}^{\ifmmode\pm\else\textpm\fi ...

Leptonic charge and weak neutrino-lepton interactions

Soviet Physics Journal, 1971
A scheme is discussed according to which the system of leptons is characterized by a single leptonic charge with different values for muonic leptons and electronic leptons. The weak neutrino-lepton interaction is investigated within the framework of this scheme. “Charged” (V + A)-currents are introduced to describe the\(\tilde v_e \rightleftharpoons v_\

Tau lepton leptonic branching fractions from L3

Nuclear Physics B - Proceedings Supplements, 1995
We have measured the branching fractions of the τ lepton into electrons and muons with the L3 detector at LEP. The sample used in analysis has been collected during 1991, 1992 and 1993 around the Z peak, with an integrated luminosity of 61 pb −1 . A preliminary result yields: BR ( τ − → e − ν ¯ e ν τ ) = ( 17.69 ± 0.17
