A Comprehensive Analysis of the R2HDM Vacuum Evolution and the Induced GW and Collider Phenomenology

Lisa Biermann, Christoph Borschensky, Rafael Boto +3

Extended Higgs sectors beyond the Standard Model (BSM) allow to dynamically generate the observed baryon asymmetry of the Universe through electroweak baryogenesis and thereby solv…

NMSSMScanner: Efficient Scans in the NMSSM Parameter Space Proof of Concept

Rafael Boto, Thi Nhung Dao, Felix Egle +4

We present the first version of the new scanning tool NMSSMScanner that allows to perform efficient scans in the complex multi-parameter space of the Next-to-Minimal Supersymmetric…

Machine Learning insights on the Z3 3HDM with Dark Matter

Fernando Abreu de Souza, Rafael Boto, Miguel Crispim Romão +2

We study a 3-Higgs Doublet Model (3HDM) with an imposed Z3 symmetry, allowing for two Inert scalar doublets and one active Higgs doublet. The WIMP dark matter candidates correspond…

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…

Constraining Multi-scalars models with colliders and Dark Matter

Rafael Boto

After the observation in 2012 of a new scalar particle closely resembling the Higgs boson of the Standard Model of particle physics, there is a general consensus that there must be…

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…

BFB conditions on a class of symmetry constrained 3HDM

Rafael Boto, Jorge C. Romão, João P. Silva

We study the bounded from below (BFB) conditions on a class of three Higgs doublet models (3HDM) constrained by the symmetry groups U(1)xU(1), U(1)xZ2 and Z2xZ2. These constraints…

Current bounds on the Type-Z three Higgs doublet model

Rafael Boto, Jorge C. Romão, João P. Silva

Type-Z models, where charged leptons, up type quarks, and down type quarks each couple to a different scalar, are only possible when there are three or more Higgs doublets. We cons…

A fully basis invariant Symmetry Map of the 2HDM

Miguel P. Bento, Rafael Boto, João P. Silva +1

We derive necessary and sufficient conditions for all global symmetries of the most general two Higgs doublet model (2HDM) scalar potential entirely in terms of reparametrization i…

Basis-independent treatment of the complex 2HDM

Rafael Boto, Tiago V. Fernandes, Howard E. Haber +2

The complex 2HDM (C2HDM) is the most general CP-violating two Higgs doublet model that possesses a softly-broken symmetry. However, the physical consequences of the…
