Description
We study the isospin-breaking and electromagnetic corrections of hadronic tau decays, which can also be utilized to extract the CKM matrix element $V_{us}$. Our analysis extends previous work by Antonelli et al. using ChPT with resonances. Our findings show the importance of these corrections in distinguishing between the $\pi^- \bar{K}^0$ and $K^- \pi^0$ modes, beyond the Low approximation. The $K^-K^0$ channel is also discussed.
