The strong coupling from hadronic $\tau$-decay data including $\tau \to {\pi }^{-}{\pi }^0{\nu }_{\tau }$ from Belle

Diogo Boito, Aaron Eiben, Maarten Golterman +3

In previous work we have combined the ${\pi }^{-}{\pi }^0$, $2{\pi }^{-}{\pi }^{+}{\pi }^0$ and ${\pi }^{-}3{\pi }^0$ spectral data obtained from hadronic $\tau$ decays measured by the ALEPH and OPAL experiments, together with…
