Abstract

The MUonE experiment aims to provide a new, independent measurement of the
hadronic vacuum polarisation (HVP) contribution to the muon g-2.
Considering the disagreement between some recent lattice calculations and
dispersive determinations, a third and fully independent result is
extremely important. However, MUonE will require an unprecedented
precision of 10^-5 to solve this disagreement.

I will introduce the MUonE experiment and explain the theory behind the
our recent NNLO calculation as well as some future developments towards
N^3LO.
