Three-Higgs-Doublet Model with Generalized CP Symmetry — I. P. Ivanov¹, •M. Köpke², M. M. Mühlleitner², and D. Sokolowska³ — ¹Instituto Superior Tecnico, Lisbon, Portugal — ²KIT, Institute for Theoretical Physics, Karlsruhe, Germany — ³University of Warsaw, Institute of Theoretical Physics, Warsaw, Poland

The flaws of the Standard Model (SM) call for new physics extensions that provide answers to (at least some of) the unsolved puzzles of the SM. These models usually come with extended Higgs sectors. Higgs extensions that are constrained by specific symmetries lead to interesting phenomenological effects. In particular, multi-Higgs models with generalized CP symmetries have become an increasingly interesting field of study. In this talk, we present the 3-Higgs-doublet model with a CP4 symmetry that has recently been proposed by Ivanov and Silva. We outline the astrophysical and phenomenological consequences of this symmetry.
