Abstract: Hadronic spectral functions of tau decays have been used in the past to provide an alternative determination of the LO Hadronic Vacuum Polarization relevant for the muon (g-2). Following recent developments and results in Lattice QCD+QED calculations, I will present a study of the isospin breaking corrections of tau spectral functions from first principles at physical pion mass, based on gauge field configurations generated by the RBC/UKQCD collaboration. I will then discuss comparisons with previous phenomenological determinations and experimental results, together with future prospects.
