Scrutinizing the Mass Matrices in Three-Higgs-Doublet Models with Generalized CP Symmetries
Duarte D. Correia, Jorge C. Romao, Joao P. Silva
The paper studies three-Higgs-doublet models with a softly broken generalized CP symmetry, showing which variants are physically distinct and demonstrating that many of them can fi…
Machine Learning in the 2HDM2S model for Dark Matter
Rafael Boto, Tiago P. Rebelo, Jorge C. Romão +1
We introduce a two real scalar singlet extension of the two Higgs doublet model. We study the vacuum structure, the bounded from below conditions, the restrictions from the oblique…
Surveying the complex three Higgs doublet model with Machine Learning
Rafael Boto, João A. C. Matos, Jorge C. Romão +1
The couplings of the 125 GeV Higgs are being measured with higher precision as the Run 3 stage of LHC continues. Models with multiple Higgs doublets allow potential deviations from…
Reassessing CP Violation in the C2HDM with Machine Learning
Rafael Boto, Karim Elyaouti, Duarte Fontes +5
We provide a study of the parameter space of the complex 2-Higgs Doublet Model (C2HDM), focusing on signs of large CP-violating couplings of the 125 GeV Higgs boson with the fermio…
New features in the Z2xZ2 3HDM two component DM model
Jorge C. Romão, Rafael Boto, Pedro N. Figueiredo +1
We investigate the constraints and phenomenology of a three Higgs doublet model (3HDM) with a symmetry, featuring two inert scalar doublets that give rise to a two-c…
Unearthing large pseudoscalar Yukawa couplings with Machine Learning
Fernando Abreu de Souza, Rafael Boto, Miguel Crispim Romão +3
With the Large Hadron Collider's Run 3 in progress, the 125 GeV Higgs boson couplings are being examined in greater detail, while searching for additional scalars. Multi-Higgs fram…
