Classification of the Discrete Symmetries for the Four-Higgs-Doublet Model
Jiazhen Shao
The multi-Higgs model (NHDM) is a class of new physics models that go beyond the Standard Model with fewer assumptions, namely by postulating the existence of multiple Higgs double…

Symmetries for the 4HDM. II. Extensions by rephasing groups
Jiazhen Shao, Igor P. Ivanov, Mikko Korhonen
We continue classification of finite groups which can be used as symmetry group of the scalar sector of the four-Higgs-doublet model (4HDM). Our objective is to systematically cons…

Symmetries for the 4HDM: extensions of cyclic groups
Jiazhen Shao, Igor P. Ivanov
Multi-Higgs models equipped with global symmetry groups, either exact or softly broken, offer a rich framework for constructions beyond the Standard Model and lead to remarkable ph…
