The muon g-2 puzzle evolves: lattice SM predictions and results from e^+e^- –> hadrons experiments

Speakers: Roberto Frezzotti (University of Rome “Tor Vergata”)

I will discuss how a series of key contributions from Lattice Field Theory to the SM prediction of the leading order hadronic vacuum polarization term of the muon anomalous magnetic moment, g_μ -2, has led to unveil either problems in the experimental results for electron-positron annihilation into hadrons at the GeV scale, used so far in the “SM prediction” of g_μ -2, or signals of New Physics.
