Fermilab’s CDF experiment has recently announced a measurement of the mass of the W boson with unprecedented precision. Even more interesting, the measurement disagrees with theoretical predictions. If confirmed, this could be a very big deal. In this video, Fermilab’s Dr. Don Lincoln gives a far ranging explanation of the measurement and its significance.
