The correction to the muon anomalous magnetic moment from the pion-pole contribution to the hadronic light-by-light scattering is considered using a description of the ${\ensuremath{\pi}}^{0}\ensuremath{-}{\ensuremath{\gamma}}^{*}\ensuremath{-}{\ensuremath{\gamma}}^{*}$ transition form factor based on the large-${N}_{C}$ and short-distance properties of QCD. The resulting two-loop integrals are treated by first performing the angular integration analytically, โฆ
