Precision measurements of the electroweak mixing angle are a powerful tool for searching for new phenomena beyond the Standard Model of particle physics.
Though they did not find dark matter, they narrowed the constraints for where it might be and demonstrated a unique approach that may speed up the search for the mysterious substance, at relatively little space and cost.
A new measurement of lepton flavor universality, a key feature of the Standard Model, in decays of the W boson is more precise than all previous measurements combined.
