| dc.description.abstract | We discuss two models that are part of a class providing a common explanation for lepton flavor universality violation in b→sl+l− decays, the dark matter (DM) problem and the muon (g−2) anomaly. The B meson decays and the muon (g−2) anomalies are explained by additional one-loop diagrams with DM candidates. The models have one extra fermion field and two extra scalar fields relative to the Standard Model. The SU(3) quantum numbers are fixed by the interaction with the Standard Model fermions in a new Yukawa Lagrangian that connects the dark and the visible sectors. We compare two models, one where the fermion is a singlet and the scalars are doublets under SU(2)L and another one where the fermion is a doublet and the scalars are singlets under SU(2)L. We conclude that both models can explain all of the previously mentioned issues imultaneously, while satisfying all other flavor and DM constraints. However, there are crucial differences between how the DM constraints affect the two models leading to a noticeable difference in the allowed DM mass range. | pt_PT |
