Determination of the Michel parameters ξ and δ in leptonic τ decays
, Physics Letters B, Vol: 349, Pages: 576-584, ISSN: 0370-2693Using the ARGUS detector at the e+e- storage ring DORIS II, we have determined the Michel parameters ξ and δ of τ∓ → l∓ν ν - decays. With an integrated luminosity of 445 pb-1 around s= 10GeV, we have produced approximately 415000 τ-pairs. From this data sample, 3262 events were selected with e+e- → τ+τ- → (l±ν ν -) (π∓π+π-ν). The semihadronic decay was used as analyser of the τ-spin and made possible - owing to the spin correlations - the determination of the parity-violating Michel parameters ξ and δ in the decay τ∓ → l∓ν ν -. Simultaneously to the determination of the Michel parameters, a measurement of the τ-neutrino helicity hντ in the decay τ∓ → π∓π+π-ν was obtained. We observed hντ = -0.85-0.17+0.15 ± 0.05, ρ{variant} = 0.721 ± 0.040 ± 0.021, ξ = 1.26-0.26+0.30 ± 0.09, and ξδ = 0.77-0.16+0.18 ± 0.05. In addition, the combined ARGUS result on hντ, ρ{variant}, ξ, and ξδ are reported using this work and previous measurements. © 1995.

An upper limit for the τ neutrino mass from τ → 5π(π<sup>0</sup>)ν<inf>τ</inf> decays
, Physics Letters B, Vol: 349, Pages: 585-596, ISSN: 0370-2693From a sample of 152,000 τ decays collected by the ALEPH detector at LEP an upper limit of 24 MeV at 95% CL on the τ neutrino mass has been determined. The limit is obtained using a two dimensional likelihood fit of the visible energy and the invariant mass distribution of 25 τ → 5π(π0)ντ events. © 1995.

Measurement of the hadronic decay current in τ<sup>-</sup>→π<sup>--+</sup>v<inf> τ</inf>
, European Physical Journal C, Vol: 67, Pages: 45-55, ISSN: 0170-9739The decay τ-→π--+v τ has been studied using data collected with the OPAL detector at LEP during 1992 and 1993. The hadronic structure functions for this decay are measured model independently assuming G-parity invariance and neglecting scalar currents. Simultaneously the parity violating asymmetry parameter is determined to be {Mathematical expression}, consistent with the Standard Model prediction of γVA=1 for left-handed tau neutrinos. Models of Kühn and Santamaria and of Isgur et al. are used to fit distributions of the invariant 3π mass as well as 2π mass projections of the Dalitz plot. The model dependent mass and width of the a1 resonance are measured to be {Mathematical expression} GeV and {Mathematical expression} GeV for the Kühn and Santamaria model and {Mathematical expression} GeV and {Mathematical expression} GeV for the Isgur et al. model. The model dependent values obtained for the parity violating asymmetry parameter are γVA=0.87±0.27-0.06+0.05 for the Kühn and Santamaria model and γVA=1.10±0.31-0.14+0.13 for the Isgur et al. model. Within the Isgur et al. model the ratio of the S-and D-wave amplitudes is measured to be D/S=-0.09±0.03±0.01. © 1995 Springer-Verlag.
