HHH Whitepaper
Vuko Brigljevic, Dinko Ferencek, Greg Landsberg +31
We here report on the progress of the HHH Workshop, that took place in Dubrovnik in July 2023. After the discovery of a particle that complies with the properties of the Higgs boso…
Effective 2HDM Yukawa Interactions and a Strong First-Order Electroweak Phase Transition
Anisha, Duarte Azevedo, Lisa Biermann +2
The top quark as the heaviest particle in the Standard Model (SM) defines an important mass scale for Higgs physics and the electroweak scale itself. It is therefore a well-motivat…
2HDM interpretations of the CMS diphoton excess at 95 GeV
Duarte Azevedo, Thomas Biekötter, P. M. Ferreira
In both Run 1 and Run 2 of the LHC, the CMS collaboration has observed an excess of events in the searches for low-mass Higgs bosons in the diphoton final state at a mass of about…
CP-violation, Asymmetries and Interferences in
Duarte Azevedo, Rodrigo Capucha, António Onofre +1
We use the associated production of top-quark pairs with a generic scalar boson at the LHC to explore the sensitivity of a large set of observables to the sign of the CP mixing ang…
Benchmarking Di-Higgs Production in Various Extended Higgs Sector Models
Hamza Abouabid, Abdesslam Arhrib, Duarte Azevedo +4
We present a comprehensive study on Higgs pair production in various archetypical extended Higgs sectors such as the real and the complex 2-Higgs-Doublet Model, the 2-Higgs-Doublet…
One-loop Corrections to the Higgs Boson Invisible Decay in the Dark Doublet Phase of the N2HDM
Duarte Azevedo, Pedro Gabriel, Margarete Muhlleitner +2
The Higgs invisible decay width may soon become a powerful tool to probe extensions of the Standard Model with dark matter candidates at the Large Hadron Collider. In this work, we…
Light Higgs searches in production at the LHC
Duarte Azevedo, Rodrigo Capucha, Emanuel Gouveia +2
In this paper we propose a new reconstruction method to explore the low mass region in the associated production of top-quark pairs () with a generic scalar boson () a…
Vacuum structure of the symmetric Georgi-Machacek model
Duarte Azevedo, Pedro M. Ferreira, Heather E. Logan +1
We discuss the vacuum structure of a version of the Georgi-Machecek model with an exact symmetry acting on the triplet fields. Besides the usual custodial-symmetric…
Scalar mass dependence of angular variables in production
Duarte Azevedo, Rodrigo Capucha, António Onofre +1
In this paper we explore CP discrimination in the associated production of top-quark pairs () with a generic scalar boson () at the LHC. We probe the CP-sensitivity of…
Scattering Interference effects on Signals in MSSM Benchmark Scenarios
Abdesslam Arhrib, Duarte Azevedo, Rachid Benbrik +4
In this talk an investigation into the interference effects between the process followed by the decay and the background process $pp \to t\ba…
Signal versus Background Interference in Signals for MSSM Benchmark Scenarios
Abdesslam Arhrib, Duarte Azevedo, Rachid Benbrik +4
In this paper, we investigate sizeable interference effects between a heavy charged Higgs boson signal produced via (+ c.c.) followed by the decay $H^-\to b\bar…
Measuring the CP structure of the top Yukawa coupling in events at the LHC
Emanuel Gouveia, Ricardo Gonçalo, António Onofre +1
The ATLAS and CMS collaborations recently announced the observation of the associated production of the Higgs boson with a top quark pair () at the LHC. This process depe…
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…
One-loop contribution to dark matter-nucleon scattering in the pseudoscalar dark matter model
Duarte Azevedo, Mateusz Duch, Bohdan Grzadkowski +3
Recent dark matter (DM) direct searches place very stringent constraints on the possible DM candidates proposed in extensions of the Standard Model. There are however models where…
Testing scalar versus vector dark matter
Duarte Azevedo, Mateusz Duch, Bohdan Grzadkowski +3
We investigate and compare two simple models of dark matter (DM): a vector and a scalar DM model. Both models require the presence of two physical Higgs bosons and whic…
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…
CP tests of Higgs couplings in semileptonic events at the LHC
D. Azevedo, A. Onofre, F. Filthaut +1
The CP nature of the Higgs coupling to top quarks is addressed in this paper, in single charged lepton final states of events produced in proton-proton collisions at th…
