helps select models for 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 ( $$ ) Model changes the Standard Model prediction for $$ whilst simultaneously explaining anomalies in $$ transitions via a heavy $$ gauge boson which is spawned by a spontaneously broken gauged $$ symmetry. The 2022 CDF II measurement of $$ , which is far from the Standard Model prediction in the statistical sense, somewhat disfavours the $$ model. Here, we generalise the gauge charge assignments to the anomaly-free combination $$ and show that incorporating the 2022 CDF II measurement of $$ selects a viable domain of integers s and t. For example, $$ 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 $$ .
