Description
After the publication of the new measurement of the muon $g-2$ by the Fermilab experiment, a tension of about 4 sigma is observed with the Standard Model estimate published by the Muon g-2 theory initiative.
The theory error is completely dominated by hadronic uncertainties, namely the hadronic vacuum polarization (HVP) and the hadronic light-by-light (HLbL) contributions and the published SM value does not include the most recent lattice calculations.
In this talk, I will present a recent lattice QCD calculation of the HLbL contribution. I will discuss the main challenges of such calculations and compare the current status in view of the the future experimental precision expected in the next few years at Fermilab.
