One-prong τ decays into final states involving kaons are studied with about 161k τ + τ − events collected by the ALEPH detector from 1991 to 1995. Charged kaons are identified by dE/dx measurement, while K 0 L 's are detected through their interaction in calorimeters. Branching ratios are measured for the inclusive mode, B(τ − → K − Xν τ ) = (1.52 ± 0.04 ± 0.04)%, where X can be any system of neutral particles, and for the exclusive modesUpper limits for B(τ − → K 0 π − π 0 π 0 ν τ ) and B(τ − → K − K 0 π 0 π 0 ν τ ) are also obtained. Mass spectra in the final states are addressed in order to study the relevant dynamics.

“…In a recent calculation, Li [12] used similar assumptions to obtain B(τ − → a 1 (1260) − ην τ → π − ρ 0 ην τ ) = 2.93 × 10 −4 . In another paper, Li [13] calculated B(τ − → f 1 π − ν τ ) = 2.9 × 10 −4 , which is still somewhat smaller than the present measurement.…”

“…Belle's paper [41] cites the few existing calculations of the τ − → K − ην τ decays based on Chiral Lagrangians [45][46][47][48] and concludes that 'further detailed studies of the physical dynamics in τ decays with η mesons are required' (see also, e.g. Ref.…”

Abstract:We have studied the τ − → K − η ( ) ν τ decays within Chiral Perturbation Theory including resonances as explicit degrees of freedom. We have considered three different form factors according to treatment of final-state interactions. In increasing degree of soundness: Breit-Wigner, exponential resummation and dispersive representation. We find that although the first one fails in accounting for the data on the Kη mode, the other two approaches provide good fits to them which are sensitive to the K (1410) pole parameters, that are determined to be M K = 1330 +27 −41 MeV and Γ K = 217 +68 −122 MeV. These values are competitive with the standard determination from τ − → (Kπ) − ν τ decays. The corresponding predictions for the τ − → K − η ν τ channel respect the current upper bound and hint to the discovery of this decay mode in the near future.
