Theory Driven Evolution of the Weak Mixing Angle
Jens Erler, Rodolfo Ferro-Hernandez, Simon Kuberski
We present the first purely theoretical calculation of the weak mixing angle in the MS scheme at low energies by combining results from lattice QCD with perturbation theory. We dis…

We compute a theoretically driven prediction for the hadronic contribution to the electromagnetic running coupling at the scale using lattice QCD and state-of-the-art perturbat…

Alternative to the application of PDG scale factors
Jens Erler, Rodolfo Ferro-Hernandez
The Particle Data Group recommends a set of procedures to be applied when discrepant data are to be combined. We introduce an alternative method based on a more general and solid s…
