Muon g-2 and B Anomalies from Dark Matter

In light of the recent result of the muon g - 2 experiment and the update on the test of lepton flavor universality R-K published by the LHCb Collaboration, we systematically study for the first time a set of models with minimal field content that can simultaneously give (i) a thermal dark matter candidate; (ii) large loop contributions to b -> sll processes able to address R-K and the other B anomalies; (iii) a natural solution to the muon g - 2 discrepancy through chirally enhanced contributions. Moreover, this type of model with heavy particles and chiral enhancement can evade the strong limits from direct searches but can be tested at present and future colliders and direct-detection searches.

Automated summary

In light of recent experimental results, a set of models with minimal field content were studied for the first time, addressing dark matter, B anomalies, and the muon g-2 discrepancy. These models, utilizing heavy particles and chiral enhancement, can evade current direct search limits and be tested at present and future colliders.
