abstract

The recently reported $7\sigma$ anomaly in measurements of the W/Z mass ratio, if confirmed, will demand an extension of some kind to the standard model of particle physics. In this paper I consider whether some recently proposed models are capable, in principle, of resolving this anomaly, subject to experimental confirmation.

  1. Embeddings of the Standard Model in $E_8$

    hep-ph 2025-07 conditional novelty 5.0 of 10

    A modified E8 model puts the Standard Model inside the so(7,3) subalgebra with compact SU(3), and uses particle coordinates in four dimensions to compute several mixing angles and mass relations.
