In particle physics the term Z’-boson refers to a hypothetical higher-mass cousin of the Z-boson which is predicted by some models that extend the standard model of particle physics, such as grand unified theories (e.g. Sahoo 06).
The existence of the has been proposed as one possible explanation of the apparently observed flavour anomalies (Gauld-Goertz-Haisch 13, D’Ambrosio-Iver-Piccinini-Polosa 19)
