Measurement of the tau -lepton mass.
Beijing The mass of the ~ lepton has been measured at the Beijing Electron Positron Collider using the Beijing Spectrometer. A search near threshold for e+e-~ ~+~-was performed. Candidate events were identified by requiring that one T decay via ~ ~ ev>, and the other via 74 pvti. The mass value, obtained from a fit to the energy dependence of the T+7-cross section, is m, = 1776.9~~:~ + 0.2 MeV....

متن کاملMeasurement of the mass of the tau lepton.
A data-driven energy scan in the immediate vicinity of r pair production threshold has been performed using the Beijing Spectrometer at the Beijing Electron-Positron Collider. Approximately 5 pb-l of data, distributed over twelve scan points, have been collected. A previous mass value for the T lepton, obtained using only the ep final state, has been published. In this paper, the final BES resu...
متن کاملLepton Mass Matrix Models
The smallness and hierarchy in fermion parameters could be the result of selection rules due to an Abelian horizontal symmetry broken by a small parameter. When applied to the lepton sector, then for a large class of models, a number of interesting order of magnitude relations arise: with i < j, m(ν i)/m(ν j) ∼ sin 2 θ ij ; m(ℓ − i)/m(ℓ − j) < ∼ sin θ ij ; m(ν i)/m(ν j) > ∼ m 2 (ℓ − i)/m 2 (ℓ −...
متن کاملQuark and lepton mass textures
We review ideas for explaining the pattern of fermion masses and mixing angles based on a spontaneously broken family symmetry. 1 The form of the quark mass matrices. The fundamental parameters of the Standard Model or its supersymmetric extension that are responsible for fermion masses and mixings are the Yukawa couplings or,equivalently, the fermion mass matrix. Unfortunately we do not have s...
