Decays $τ \to 3 K ν_{τ}$ in $U (3) \times U (3)$ quark NJL model

M. K. Volkov, A. A. Pivovarov, K. Nurlan

The widths of the decays $τ \to K^{-} K^{+} K^{-} ν_{τ}$ and $τ \to K^{-} K^{0} K ˉ^{0} ν_{τ}$ are calculated in the $U (3) \times U (3)$ chiral quark NJL model. Four channels are considered: conta…

Strong coupling constant from $τ$ decay within renormalization scheme invariant treatment

J. G. Koerner, F. Krajewski, A. A. Pivovarov

We extract a numerical value for the strong coupling constant α_s from the τ-lepton decay rate into nonstrange particles. A new feature of our procedure is the explicit use of reno…
