The hadronic contribution to the running of the electromagnetic coupling and electroweak mixing angle
The hadronic contribution to the running of the electromagnetic coupling and electroweak mixing angle
As present and future experiments, on both the energy and precision frontiers, look to identify new physics beyond the Standard Model, we require more precise determinations of fundamental quantities, like the QED and electroweak couplings at various momenta. These can be obtained either entirely from experimental measurements, or from one …
