چکیده
The momenta of τ decay products in the reaction e + e − → τ + τ − do not constrain the τ direction unambiguously. It is shown how the measurement of tracks of hadrons from semileptonic τ decays, in particular their relative impact parameters, allows to resolve this ambiguity.

Reliability analysis of a robotic system using hybridized technique
In this manuscript, the reliability of a robotic system has been analyzed using the available data (containing vagueness, uncertainty, etc). Quantification of involved uncertainties is done through data fuzzification using triangular fuzzy numbers with known spreads as suggested by system experts. With fuzzified data, if the existing fuzzy lambda–tau (FLT) technique is employed, then the comput...
متن کاملOn $Phi$-$tau$-quasinormal subgroups of finite groups
Let $tau$ be a subgroup functor and $H$ a $p$-subgroup of a finite group $G$. Let $bar{G}=G/H_{G}$ and $bar{H}=H/H_{G}$. We say that $H$ is $Phi$-$tau$-quasinormal in $G$ if for some $S$-quasinormal subgroup $bar{T}$ of $bar{G}$ and some $tau$-subgroup $bar{S}$ of $bar{G}$ contained in $bar{H}$, $bar{H}bar{T}$ is $S$-quasinormal in $bar{G}$ and $bar{H}capbar{T}leq bar{S}Phi(bar{H})$. I...
متن کاملMeasurement of the tau polarisation at the Z resonance
Using 18.8 p b ~ of data collected in 1990 and 1991, ALEPH has measured the tau polarisation in the decay modes z ~ e v q , r--*/zv~7, z ~ z v , r -*pv and r ~ a a v, using both the individual tau decay kinematics and the event acollinearity. The measurement of the tau polarisation as a function of the production polar angle yields the two parameters sZ~ and ~Ze, where d r = l l l ) 2 2gvgA/[(g...
متن کاملUse of the Dowell Bryant Incontinence Cost Index as a post-treatment outcome measure after non-surgical therapy.
The aim of this study was to use the previously validated Dowell Bryant Incontinence Cost Index (DBICI) as a post-treatment outcome measure after non-surgical therapy and to determine whether the magnitude of reduced leakage would correlate with the magnitude of reduced personal cost. A simple urethral occlusive device (Femassist) was employed in 57 women with stress, urge, or mixed incontinenc...
متن کاملNew CLEO Results on Tau Physics
New, preliminary tau physics results are reported from tau-pair data acquired with the CLEO 11 detector operating at the Cornell Electron Storage Ring. The tau m~s is measured as m, = 1777.6 + 0.9 + 1.5 MeV/cz by exploiting the kinematics of events in which both taus decay hadronicdly. The electronic branching fraction is determined to be B,=O. 1742+0.0015+0.0023 by counting di-electron tau-pai...
