# The hadronic contribution to the running of the electromagnetic coupling and the electroweak mixing angle

@article{C2020TheHC, title={The hadronic contribution to the running of the electromagnetic coupling and the electroweak mixing angle}, author={M. C{\`e} and T.

The electromagnetic coupling $\alpha$ and the electroweak mixing angle $\theta_{\mathrm{W}}$ are parameters of the Standard Model (SM) that enter precision SM tests and play a fundamental r\^ole in beyond SM physics searches. Their values are energy dependent, and non-perturbative hadronic contributions are the main source of uncertainty to the theoretical knowledge of the running with energy. We present a lattice study of the leading hadronic contribution to the running of $\alpha$ and $\sin^2…
