Content
The well-known discrepancy in the muon $g-2$ between experiment and theory
demands further theory investigations in view of the upcoming new experiments.
One of the leading uncertainties lies in the hadronic light-by-light scattering
contribution (hlbl), that we address with our position-space approach. In this
talk we will focus on exploratory studies of a fermion loop without gluon
exchanges on the lattice and in the continuum. These studies provide us with
useful information for our planned computation of hlbl $g-2$ using full QCD.
