The hadronic light-by-light contribution to the muon anomalous magnetic
moment and renormalization group for EFT    [PDF]

Johan Bijnens, Mehran Zahiri Abyaneh

We give a short overview of the theory of the muon anomalous magnetic moment with emphasis on the hadronic light-by-light and the pion loop contribution. We explain the difference between the hidden local symmetry and full VMD pion loop and discuss leading logarithms in the anomalous sector of 2-flavour chiral perturbation theory.
