Description

In this talk we review the status of the lattice calculation of the Hadronic Vacuum Polarization (HVP) contribution to $a_\mu=(g-2)_\mu$ from the ETM collaboration.
Our result includes the effects of the $u,d,s,c$ quarks in the isospin-symmetric limit of QCD. Our ensembles are generated with $N_f=2+1+1$ dynamical flavors through Wilson-clover twisted mass fermions, and our correlators are tuned at physical point to permille precision.
