On 7 April, researchers announced results from the now-defunct Tevatron collider in Illinois finding that the mass of the W boson is higher than the standard model of particle physics predicts – a shockingly solid measurement that could demand new physics. Ideas to explain it have already begun flowing in earnest.

The W boson is one of the particles that carries the weak nuclear force in the same way that a photon carries electromagnetic force. …
