Scrutinizing the Mass Matrices in Three-Higgs-Doublet Models with Generalized CP Symmetries
Duarte D. Correia, Jorge C. Romao, Joao P. Silva
We investigate three-Higgs-doublet models with a softly broken generalized CP (GCP) symmetry, focusing on the Yukawa sector and its compatibility with quark flavor data. We first s…
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…
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…
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…
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…
Dark matter stabilized by a non-abelian group: lessons from the 3HDM
Hong Deng, Rafael Boto, Igor P. Ivanov +1
When building dark matter (DM) models, one often imposes conserved discrete symmetries to stabilize DM candidates. The simplest choice is but models with larger sta…
Large pseudoscalar Yukawa couplings in the complex 3HDM
Rafael Boto, Luis Lourenco, Jorge C. Romão +1
As LHC's Run3 unfolds, we peer deeper into the couplings of the 125GeV Higgs () and also test for extra scalars. Even before such extra scalars are found, one can probe th…
Novel two component dark matter features in the 3HDM
Rafael Boto, Pedro N. Figueiredo, Jorge C. Romão +1
We discuss the constraints and phenomenology of the three Higgs doublet model (3HDM) with two inert scalars, originating two dark matter (DM) particles. We elucida…
New physics interpretations for nonstandard values of
Rafael Boto, Dipankar Das, Jorge C. Romao +2
Current measurement of the signal strength invite us to speculate about possible new physics interactions that exclusively affect without altering the other sign…
Fingerprinting the Type-Z three Higgs doublet models
Rafael Boto, Dipankar Das, Luis Lourenco +2
There has been great interest in a model with three Higgs doublets in which fermions with a particular charge couple to a single and distinct Higgs field. We study the phenomenolog…
