%X We report on our computation of the pion transition form factor <span style="font-family:helvetica"><i>F</i><sub>P→ γ<sup>*</sup>γ<sup>*</sup></sub> from twisted mass lattice QCD in order to determine the numerically dominant light pseudoscalar pole contribution in the hadronic light-by-light scattering contribution to the anomalous magnetic moment of the muon a<sub>μ</sub> = (g−2)<sub>μ</sub>. The pion transition form factor is computed directly at the physical point. We present first results for our estimate of the pion-pole contribution with kinematic setup for the pion at rest.
