ALBRECHT 1998 use tau pair events of the type ${{\mathit \tau}^{-}}$ ${{\mathit \tau}^{+}}$ $\rightarrow({{\mathit \ell}^{-}}{{\overline{\mathit \nu}}_{{{{{\mathit \ell}}}}}}{{\mathit \nu}_{{{\tau}}}})({{\mathit \pi}^{+}}{{\mathit \pi}^{0}}{{\overline{\mathit \nu}}_{{{\tau}}}}$), and their charged conjugates.

ALBRECHT 1995 use tau pair events of the type ${{\mathit \tau}^{-}}$ ${{\mathit \tau}^{+}}$ $\rightarrow$ (${{\mathit \ell}^{-}}{{\overline{\mathit \nu}}_{{{{{\mathit \ell}}}}}}{{\mathit \nu}_{{{\tau}}}}$ ) (${{\mathit h}^{+}}{{\mathit h}^{-}}{{\mathit h}^{+}}$ (${{\mathit \pi}^{0}}$ ) ${{\overline{\mathit \nu}}_{{{\tau}}}}$ ) and their charged conjugates.

ALBRECHT 1993G use tau pair events of the type ${{\mathit \tau}^{-}}$ ${{\mathit \tau}^{+}}$ $\rightarrow$ (${{\mathit \mu}^{-}}{{\overline{\mathit \nu}}_{{{\mu}}}}{{\mathit \nu}_{{{\tau}}}}$ ) (${{\mathit e}^{+}}{{\mathit \nu}_{{{e}}}}{{\overline{\mathit \nu}}_{{{\tau}}}}$ ) and their charged conjugates.
