Abstract

Hadronic light-by-light scattering in the anomalous magnetic moment of the muon $a_\mu$ is one of two hadronic effects limiting the precision of the Standard Model prediction for this precision observable, and hence the new-physics discovery potential of direct experimental determinations of $a_\mu$. In this contribution, I report on recent progress in the calculation of this effect achieved both via dispersive and lattice QCD methods.

Report

These proceedings describe the latest developments in the calculation of the Hadronic Light-by-Light scattering to the anomalous magnetic moment of the muon and represent an important contribution to our understanding of lepton physics. I recommend it for publication.
