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 tau -lepton lifetime.
We measure the T lepton lifetime with r+rpairs in which one or both of the T’S decays to three charged particles. The data were. collected with the CLEO II detector operating at the electron-positron collider CESR at energies on and near the Y(4.T). We use displacements of the three-track vertices to determine the 7 lifetime. The result is r7 = 289.0f 2.8 f 4.0 fs. PACS: 13.1O.+q; 13.35.+s
متن کاملCan the Higgs Sector Be Probed in Tau-Lepton Decays?
It is unlikely that a high statistics study of r-lepton decays will be sensitive to the Higgs boson sector of electroweak physics. A Tau-Charm Factory is an ideal facility for the study of rare deca.ys of the rlepton. At a machine discussed in these Proceedings, one might expect to produce on the order of lo7 r’s per year. It is an interesting exercise to consider whether such a data sample is ...
متن کاملThe Tau Lepton*
This paper reviews the present experimental knowledge of the properties of the tau lepton and the tau neutrino. The conventional theory of lepton properties and interactions is summarized; and that theory is compared with experiment. Future directions for research in tau and tau neutrino physics are described.
متن کاملMSSM Higgs searches with tau lepton final states in CMS
The Standard Model [1] of strong and electroweak interactions is in excellent agreement with the experimental measurements. However, the core of the theory, the electroweak symmetry breaking manifesting itself in the heavy vector bosonsW and Z and the massless photon, is the least known sector of the model. The Higgs mechanism [2] provides a mathematical explanation to this phenomenon, and one ...
