Description
Recently, the hadronic vacuum polarization contribution to the anomalous
magnetic moment of the muon was determined by the BMW collaboration with
sub-percent precision. Such a precision requires to
control many sources of uncertainty. One of these is the uncertainty
in the determination of the lattice spacing.
In this talk, we present the scale setting entering this computation. It
relies on the mass of the Omega baryon as input which is directly used to set
the scale of our main calculation. It also allows us to calculate the
value of the intermediate scale setting quantity $w_0$. Here, we present
our calculation of this quantity with a relative precision of about 0.4%.
