The hadronic running of the electroweak couplings from lattice QCD
The hadronic running of the electroweak couplings from lattice QCD
The energy dependency (running) of the strength of electromagnetic interactions $\alpha$ plays an important role in precision tests of the Standard Model. The running of the former to the $Z$ pole is an input quantity for global electroweak fits, while the running of the mixing angle is susceptible to the …
