Idea

The W- and Z-bosons are the quanta of the electroweak field,vector boson in the standard model of particle physics.

A hypothetical high-mass cousin of the Z-boson is the Z'-boson.

Mass discrepancy

The following article claims that this mass discrepancy is compatible with (in fact predicted by, see footnote 3) the observed flavour anomalies:
