Why are we still measuring the mass of the W boson | Explainer

The W boson is a fundamental particle in physics in the Standard Model, which describes how particles and forces interact. The W boson is responsible for mediating the weak nuclear force, one of the four fundamental forces of nature alongside gravity, electromagnetism, and the strong nuclear force.

40 years since the discovery of the W boson, its measurement is still a hot topic. Small variations in its measured value could indicate the presence of new physics beyond the Standard Model.

In the video, we explain why this is the case.
