HiggsTools: BSM scalar phenomenology with new versions of HiggsBounds and HiggsSignals
Henning Bahl, Thomas Biekötter, Sven Heinemeyer +4
The codes HiggsBounds and HiggsSignals compare model predictions of BSM models with extended scalar sectors to searches for additional scalars and to measurements of the detected H…
The CN2HDM
M. Mühlleitner, J. Müller, S. L. Williamson +1
We present the CP-violating Next-to-2-Higgs-Doublet Model (CN2HDM) which is based on the extension of the CP-violating 2-Higgs-Doublet-Model (C2HDM) by a complex singlet field that…
Publishing statistical models: Getting the most out of particle physics experiments
Kyle Cranmer, Sabine Kraml, Harrison B. Prosper +30
The statistical models used to derive the results of experimental analyses are of incredible scientific value and are essential information for analysis preservation and reuse. In…
Testing Exotic Scalars with HiggsBounds
Henning Bahl, Victor Martin Lozano, Tim Stefaniak +1
The program HiggsBounds is a well-established tool for testing Beyond-the-Standard Model (BSM) theories with an extended Higgs sector against experimental limits from collider sear…
The forgotten channels: charged Higgs boson decays to a and a non-SM-like Higgs boson
Henning Bahl, Tim Stefaniak, Jonas Wittbrodt
The presence of charged Higgs bosons is a generic prediction of multiplet extensions of the Standard Model (SM) Higgs sector. Focusing on the Two-Higgs-Doublet-Model (2HDM), we dis…
HiggsSignals-2: Probing new physics with precision Higgs measurements in the LHC 13 TeV era
Philip Bechtle, Sven Heinemeyer, Tobias Klingl +3
The program HiggsSignals confronts the predictions of models with arbitrary Higgs sectors with the available Higgs signal rate and mass measurements, resulting in a likelihood esti…
ScannerS: Parameter Scans in Extended Scalar Sectors
Margarete Mühlleitner, Marco O. P. Sampaio, Rui Santos +1
We present the public code ScannerS-2 that performs parameter scans and checks parameter points in theories beyond the Standard Model (BSM) with extended scalar sectors. ScannerS i…
HiggsBounds-5: Testing Higgs Sectors in the LHC 13 TeV Era
Philip Bechtle, Daniel Dercks, Sven Heinemeyer +4
We describe recent developments of the public computer code HiggsBounds. In particular, these include the incorporation of LHC Higgs search results from Run 2 at a center-of-mass e…
The Dark Phases of the N2HDM
Isabell Engeln, Pedro M. Ferreira, M. Margarete Mühlleitner +2
We discuss the dark phases of the Next-to-2-Higgs Doublet model. The model is an extension of the Standard Model with an extra doublet and an extra singlet that has four distinct C…
Reinterpretation of LHC Results for New Physics: Status and Recommendations after Run 2
Waleed Abdallah, Shehu AbdusSalam, Azar Ahmadov +139
We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpret…
Two-real-scalar-singlet extension of the SM: LHC phenomenology and benchmark scenarios
Tania Robens, Tim Stefaniak, Jonas Wittbrodt
We investigate the LHC phenomenology of a model where the Standard Model (SM) scalar sector is extended by two real scalar singlets. A discrete s…
Vacuum Instabilities in the N2HDM
P. M. Ferreira, Margarete Mühlleitner, Rui Santos +2
The Higgs sector of the Next-to-Minimal Two-Higgs-Doublet Model (N2HDM) is obtained from the Two-Higgs-Doublet Model (2HDM) containing two complex Higgs doublets, by adding a real…
Impact of Vacuum Stability Constraints on the Phenomenology of Supersymmetric Models
Wolfgang G. Hollik, Georg Weiglein, Jonas Wittbrodt
We present a fast and efficient method for studying vacuum stability constraints in multi-scalar theories beyond the Standard Model. This method is designed for a reliable use in l…
The CLIC Potential for New Physics
J. de Blas, R. Franceschini, F. Riva +100
The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics. It combines the benefits of the clean environment of colliders with operation…
Models with Extended Higgs Sectors at Future Colliders
Duarte Azevedo, Pedro Ferreira, M. Margarete Mühlleitner +2
We discuss the phenomenology of several Beyond the Standard Model (SM) extensions that include extended Higgs sectors. The models discussed are: the SM extended by a complex single…
CP in the dark
Duarte Azevedo, P. M. Ferreira, M. Margarete Muhlleitner +3
We build a model containing two scalar doublets and a scalar singlet with a specific discrete symmetry. After spontaneous symmetry breaking, the model has Standard Model-like pheno…

The program N2HDECAY calculates the branching ratios and decay widths of the Higgs bosons of the Next-to-Two-Higgs-Doublet Model (N2HDM). The code incorporates the dominant higher-…
The C2HDM revisited
Duarte Fontes, Margarete Mühlleitner, Jorge C. Romão +3
The complex two-Higgs doublet model is one of the simplest ways to extend the scalar sector of the Standard Model to include a new source of CP-violation. The model has been used a…
The CP-Violating 2HDM in Light of a Strong First Order Electroweak Phase Transition and Implications for Higgs Pair Production
