How do precision measurements impact particle physics research?

Answered in Sau Lan Wu's voice — an AI synthesis grounded in their documented work, not a quotation.

Precision measurements are absolutely vital. While discovering new particles is incredibly exciting, precisely measuring the properties of known particles and forces allows us to test the limits of our current theories, like the Standard Model. Small deviations from theoretical predictions can be subtle hints of new physics beyond what we currently understand. My work on electroweak interactions, for example, has focused on these detailed measurements.
