摘要
We study a variation of the Krauss-Nasri-Trodden model with a colored triplet scalar field and a colored singlet scalar field. We discuss the anomaly coming from b→sμμ, fit to the muon anomalous magnetic moment and the relic density of the Majorana-type dark matter candidate, and satisfy various constraints such as lepton flavor violations and flavor-changing neutral currents. Also, we discuss the direct constraints from the collider searches and the possibilities of detecting the new fields at the LHC.
