Singlet scalar and 2HDM extensions of the Standard Model: CP-violation and constraints from $(g - 2)_{μ}$ and $e$ EDM

Venus Keus, Niko Koivunen, Kimmo Tuominen

We study popular scalar extensions of the Standard Model, namely the singlet extension, the 2-Higgs doublet model (2HDM) and its extension by a singlet scalar. We focus on the cont…

Froggatt-Nielsen mechanism in a model with $S U (3)_{c} \times S U (3)_{L} \times U (1)_{X}$ gauge group

Katri Huitu, Niko Koivunen

The models with the gauge group $S U (3)_{c} \times S U (3)_{L} \times U (1)_{X}$ (331-models) have been advocated to explain why there are three fermion generations in Nature. As such they ca…
