We explore the possibilities in two-Higgs-doublet models (2HDMs) of Type I and Type II for Higgs states with mass below about 60 GeV, i.e. less than half of the ~125 GeV mass of the observed SM-like Higgs boson. We identify the latter as either the lighter or the heavier CP-even state, h or H, and employ scans of the 2HDM parameter space taking into account all relevant theoretical and experimental constraints, including the most up-to-date Higgs signal strength measurements. We find that, in… 
A 96 GeV Higgs Boson in the 2HDM plus Singlet
We discuss a ∼ 3σ signal (local) in the light Higgs-boson search in the diphoton decay mode at ∼ 96 GeV as reported by CMS, together with a ∼ 2σ excess (local) in the bb̄ final state at LEP in the
The 28 GeV Dimuon Excess in Lepton Specific 2HDM
We explore the Higgs mass spectrum in a class of Two Higgs Doublet Models (2HDMs) in which a scalar SU(2)_L oublet interacts only with quarks, while the second one interacts only with leptons. The
Scrutinizing the alignment limit in two-Higgs-doublet models: m h = 125 GeV
In the alignment limit of a multi-doublet Higgs sector, one of the Higgs mass eigenstates aligns in field space with the direction of the scalar field vacuum expectation values, and its couplings
Search for New Light Higgs Bosons in Boosted Tau Final States with the CMS Experiment
In this dissertation, I present a search for non-standard decays of a Standard Model-like Higgs boson to pairs of light bosons, as predicted in models with extended Higgs sectors. In two Higgs
Prospects for Higgs physics at energies up to 100 TeV.
The prospects for Higgs boson physics at future proton-proton colliders with centre of mass (c.m.) energies up to 100 TeV are summarized and the sensitivity of a 100 Tev proton machine to probe the new Higgs states is discussed and compared to that of the LHC with a c.m. energy of 14 TeV.
Isospin-violating dark-matter-nucleon scattering via two-Higgs-doublet-model portals
We show that in a multi-Higgs model in which one Higgs fits the LHC 125 GeV state, one or more of the other Higgs bosons can mediate DM-nucleon interactions with maximal DM isospin violation being
Update of global Two-Higgs-Doublet model fits
A bstractWe perform global fits of Two-Higgs-Doublet models with a softly broken ℤ2 symmetry to recent results from the LHC detectors CMS and ATLAS, that is signal strengths and direct search limits
Search for a lighter Higgs boson in Two Higgs Doublet Models
A bstractWe consider present constraints on Two Higgs Doublet Models, both from the LHC at Run 1 and from other sources in order to explore the possibility of constraining a neutral scalar or
Discovery prospects of a light Higgs boson at the LHC in type-I 2HDM
We present a comprehensive analysis of observing a light Higgs boson in the mass range $70$ -- $110$ GeV at the 13/14 TeV LHC, in the context of the type-I two-Higgs-doublet model. The decay of the
Dark Matter through the Higgs portal
We review scenarios in which the particles that account for the Dark Matter (DM) in the Universe interact only through their couplings with the Higgs sector of the theory, the so-called Higgs-portal


Constraints on and future prospects for Two-Higgs-Doublet Models in light of the LHC Higgs signal
We analyze the Two-Higgs-Doublet Models (2HDMs) of Type I and II for consistency with the latest measurements of the ~125.5 GeV Higgs-like signal at the LHC. To this end, we perform scans of the 2HDM
A light Higgs scalar in the NMSSM confronted with the latest LHC Higgs data
A bstractIn the Next-to-Minimal Supersymemtric Standard Model (NMSSM), one of the neutral Higgs scalars (CP-even or CP-odd) may be lighter than half of the SM-like Higgs boson. In this case, the
The CP-conserving two-Higgs-doublet model: the approach to the decoupling limit
A CP-even neutral Higgs boson with standard-model-like couplings may be the lightest scalar of a two-Higgs-doublet model. We study the decoupling limit of the most general CP-conserving
Probing wrong-sign Yukawa couplings at the LHC and a future linear collider
We consider the two-Higgs-doublet model as a framework in which to evaluate the viability of scenarios in which the sign of the coupling of the observed Higgs boson to down-type fermions (in
MSSM Higgs boson searches at the LHC: benchmark scenarios after the discovery of a Higgs-like particle
A Higgs-like particle with a mass of about 125.5 GeV has been discovered at the LHC. Within the current experimental uncertainties, this new state is compatible with both the predictions for the
Wrong sign and symmetric limits and non-decoupling in 2HDMs
A bstractWe analyse the possibility that, in two Higgs doublet models, one or more of the Higgs couplings to fermions or to gauge bosons change sign, relative to the respective Higgs Standard Model
Probing the two light Higgs scenario in the NMSSM with a low-mass pseudoscalar
A bstractIn this article we propose a simultaneous collider search strategy for a pair of scalar bosons in the NMSSM through the decays of a very light pseudoscalar. The massive scalar has a mass
Exotic decays of the 125 GeV Higgs boson
We perform an extensive survey of nonstandard Higgs decays that are consistent with the 125 GeV Higgs-like resonance. Our aim is to motivate a large set of new experimental analyses on the existing
Higgs bosons in supersymmetric models, 1
Abstract We describe the properties of Higgs bosons in a class of supersymmetric theories. We consider models in which the low-energy sector contains two weak complex doublets and perhaps one complex
Supersymmetric exotic decays of the 125 GeV Higgs boson.
A set of novel decay topologies for the 125 GeV Higgs boson in supersymmetry which are initiated by its decay into a pair of neutralinos are revealed, and these exotic decays open a new avenue for exploring new physics couplings with the 125-GeVHiggs bosons at colliders.
