[Formula: see text] helps select [Formula: see text] models for [Formula: see text] anomalies

As shown in Allanach et al. (Global fits of third family hypercharge models to neutral current B-anomalies and electroweak precision observables. arXiv:2103.12056), the Third Family Hypercharge ([Formula: see text] ) Model changes the Standard Model prediction for [Formula: see text] whilst simultaneously explaining anomalies in [Formula: see text] transitions via a heavy [Formula: see text] gauge boson which is spawned by a spontaneously broken gauged [Formula: see text] symmetry. The 2022 CDF II measurement of [Formula: see text] , which is far from the Standard Model prediction in the statistical sense, somewhat disfavours the [Formula: see text] model. Here, we generalise the gauge charge assignments to the anomaly-free combination [Formula: see text] and show that incorporating the 2022 CDF II measurement of [Formula: see text] selects a viable domain of integers s and t. For example, [Formula: see text] yields a p value of .08 in a two-parameter global fit to 277 electroweak and flavour changing b data, much improving a SM p value of [Formula: see text] .
