Isospin-breaking corrections to ${\tau }^{-}\to {\pi }^{-}{\pi }^0{\nu }_{\tau }$ decays and the muon $g-2$

J. A. Miranda

We review the isospin-breaking and electromagnetic corrections to the ${\tau }^{-}\to {\pi }^{-}{\pi }^0{\nu }_{\tau }$ decays, which are used as an input to the two-pion contributions to the hadronic vacuum…
