Tau Physics
The τ lepton is a member of the third generation which decays into particles belonging to the first and second ones. Thus, τ physics could provide some clues to the puzzle of the recurring families of leptons and quarks. One naïvely expects the heavier fermions to be more sensitive to whatever dynamics is responsible for the fermion–mass generation. The pure leptonic or semileptonic character o...
متن کاملTau physics
The pure leptonic or semileptonic character of τ decays makes them a good laboratory to test the structure of the weak currents and the universality of their couplings to the gauge bosons. The hadronic τ decay modes constitute an ideal tool for studying low–energy effects of the strong interactions in very clean conditions; a well–known example is the precise determination of the QCD coupling f...
متن کاملTau Physics: Theoretical Perspective
The leptonic decays of the τ lepton provide relevant tests on the structure of the weak currents and the universality of their couplings to the gauge bosons. The hadronic τ decay modes constitute an ideal tool for studying low–energy effects of the strong interaction in very clean conditions. Accurate determinations of the QCD coupling and the strange quark mass have been obtained with τ decay ...
متن کاملStatus of Tau Physics
We review, very briefly, many of the important results arising in the study of tau lepton production and decay, with emphasis on recent results. We discuss the studies of topological and exclusive branching fractions, inclusive semi-leptonic tau decay spectral functions, extraction of QCD parameters including αS and the strange quark mass, exclusive semileptonic decays and low energy meson dyna...
متن کاملTau Charm Factory Physics
Physics from a Tau Charm Factory is presented. . T au Charm Factories proposed for future machines will provide powerful and unique facilities to study a variety of physics topics: the tau lepton, charm mesons, charmonium and the J/vdecays. These topics cover the physics of the members of the first and second quark doublets and the third lepton doublet. The number of Table. 1 Tau Charm Factory ...
