Abstract
We revisit the isospin-breaking and electromagnetic corrections to some hadronic tau decays, which can also be employed to extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element Vus. We extend former analyses by Antonelli et al. working with ChPT with resonances. We find that going beyond the Low approximation, these corrections play an important role between the π−K¯0 and K−π0 modes.
