Mattia Bruno - Isospin breaking in tau input for (g-2)_mu from Lattice QCD

Aula F (Via della Vasca Navale 84)


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.
