Precision lattice calculation of the hadronic contribution to the running of the electroweak gauge couplings

Alessandro Conigli, Dalibor Djukanovic, Georg von Hippel +6

We present an update of our lattice QCD determination of the hadronic contribution to the running of the electromagnetic coupling, $\Delta {\alpha }_{\mathrm{had}}^{(5)}(-Q^2)$, and of the elect…
