Hadronic contributions to $\alpha (Q^2)$ and ${\sin }^2{\theta }_W(Q^2)$ from spectral reconstruction of lattice-QCD data

Adrián del Pino, David A. Clarke, Carleton DeTar +17

We present preliminary results from a lattice-QCD study of the hadronic contributions to the running of the electromagnetic coupling, $\Delta \alpha (Q^2)$, and the electroweak mixing angle, $…
