چکیده
We present the first observation of τ lepton decays to hadronic final states with a φ-meson. This analysis is based on 401 fb of data accumulated at the Belle experiment. The branching fraction obtained is B(τ− → φK−ντ ) = (4.05 ± 0.25 ± 0.26) × 10.

Within the resonance chiral theory (RχT), we have studied the process of a tau lepton decaying into a vector resonance plus a pseudo-Goldstone meson and a tau neutrino. Two kinds of processes are discussed: (a) τ− → (ρπ, ωπ−, φπ,KK)ντ , belonging to ∆S = 0 processes and (b) ∆S = 1 processes, such as τ− → (ρK, ωK−, φK−,K ∗0 π−)ντ . To fit the τ − → ωπ−ντ spectral function and the decay distribut...
متن کاملSecond - class current in τ → πην analysis and measurement of τ → hh ′ h ′ ′ ν from Belle ∼ Electroweak physics from Belle ∼
Based on a 670 fb −1 data sample accumulated at the Belle detector, we have looked for a second-class current decays τ → πην and τ → πη (958)ν. First possible indications for the τ → πην decay are attained with a 2.4 significance corresponding to the branching fraction B(τ − → π − ην τ) = (4.4 ± 1.6 ± 0.8) × 10 −5 or B < 7.3 × 10 −5 at 90% confidence level. Also, the upper limit on B(τ − → π − ...
متن کاملLeptons and Photons
It is assumed that three lepton families (ν e , e), (ν µ , µ), (ν τ , τ) carry charges, which are sources of electronic, muonic and tauonic massless vector particles, respectively. Various manifestations of these hypothetical photons are discussed. We know only one photon that is coupled to the electric charge of particles. One of the most fundamental properties of the electric charge is its co...
متن کاملIsospin Violation in τ → 3πντ
Isospin violating signals in the τ − → (3π) − ν τ decay mode are discussed. For the τ − → π − π − π + ν τ decay mode, isospin violation arises from the vector current contribution in the τ − → ωπ − ν τ decay with the subsequent isospin violating ω decay into π + π −. We demonstrate that such effects may be observed in presently available data through the measurement of the interference effects ...
