4 Jan 2023 | Abstract: | Recent CDF II collaboration results on $W$ mass measurements contradict
Standard Model~(SM) prediction, requiring new physics to explain this anomaly.
To explain this issue, in this paper we investigate the idea of using the
$U(1)_{B-L}$ gauged SM extension. We demonstrate that $B-L$ extended models can
explain the revised best fit values for $S$, $T$, and $U$ following the CDF II
results. We studied the parameter space of models with and without mixing
between neutral gauge bosons. We also reviewed the dark matter constraints and
demonstrated that there is parameter space which is compatible with current $W$
boson mass, relic abundance, and direct detection experiments. | Source: | arXiv, 2301.01522 | Services: | Forum | Review | PDF | Favorites |
