Abstract

We report on our preliminary results from the lattice-QCD computation of the hadronic light-by-light (HLbL) contribution to the anomalous magnetic moment of the muon. We use twisted-mass N_f = 2 + 1 + 1 gauge ensembles at the physical point generated by the Extended Twisted Mass Collaboration (ETMC).
