• #### CP-Violation in the $ZZZ$ and $ZWW$ vertices at $e^+e^-$ colliders in Two-Higgs-Doublet Models ﻿

(Springer, 2016-05)
We discuss possibilities of measuring CP violation in the Two-Higgs-Doublet Model by studying effects of one-loop generated $ZZZ$ and $ZWW$ vertices. We discuss a set of CP-sensitive asymmetries for $ZZ$ and $W^+W^-$ ...

• #### Diagnosing CP properties of the 2HDM ﻿

(Springer, 2014-01)
We have investigated a Two-Higgs-Doublet Model (2HDM), focusing on CP violation. Various scenarios with spontaneous and explicit breaking of CP have been considered. Some features of CP violation related to a choice of the ...

• #### Exploring the CP-violating Inert-Doublet Model ﻿

(Springer, 2011-06-01)
We have explored properties of an extension of the Inert Doublet Model by the addition of an extra non-inert scalar doublet. The model offers a possibility of CP violation in the scalar sector and a candidate for the ...

• #### Measuring CP violation in two-Higgs-doublet models in light of the LHC Higgs data ﻿

(Springer, 2014-11)
In Two-Higgs-Doublet models, the conditions for CP violation can be ex- pressed in terms of invariants under U(2) rotations among the two SU(2) Higgs doublet fields. In order to design a strategy for measuring the ...

• #### Probing the charged Higgs boson at the LHC in the CP-violating type-II 2HDM ﻿

(Springer, 2012-11-05)
We present a phenomenological study of a CP-violating two-Higgs-doublet Model with type-II Yukawa couplings at the Large Hadron Collider (LHC). In the light of recent LHC data, we focus on the parameter space that survives ...

• #### Search for additional heavy neutral Higgs and gauge bosons in the ditau final state produced in 36 fb−1 of pp collisions at s√=13 TeV with the ATLAS detector ﻿

(Springer, 2018-01-12)
A search for heavy neutral Higgs bosons and Z′ bosons is performed using a data sample corresponding to an integrated luminosity of 36.1 fb^−1 from proton-proton collisions at √s=13 TeV recorded by the ATLAS detector at ...
Journal article
• #### Search for anomalous production of prompt same-sign lepton pairs and pair-produced doubly charged Higgs bosons with $\sqrt{s}$ = 8 TeV $pp$ collisions using the ATLAS detector ﻿

(Springer, 2015-03-09)
A low-background inclusive search for new physics in events with same-sign dileptons is presented. The search uses proton--proton collisions corresponding to 20.3 fb$^{-1}$ of integrated luminosity taken in 2012 at a ...

• #### Search for heavy resonances decaying into a W or Z boson and a Higgs boson in final states with leptons and b-jets in 36 fb−1 of √s=13 TeV pp collisions with the ATLAS detector ﻿

(Springer Berlin Heidelberg, 2018-03-28)
A search is conducted for new resonances decaying into a W or Z boson and a 125 GeV Higgs boson in the 𝜈𝜈⎯⎯⎯𝑏𝑏⎯⎯⎯ , ℓ±𝜈𝑏𝑏⎯⎯⎯ , and ℓ+ℓ−𝑏𝑏⎯⎯⎯ final states, where ℓ± = e± or μ±, in pp collisions at 𝑠√=13 ...

• #### Search for Higgs boson decays to beyond-the-Standard-Model light bosons in four-lepton events with the ATLAS detector at √s=13 TeV ﻿

(Springer Berlin Heidelberg, 2018-06-29)
A search is conducted for a beyond-the-Standard-Model boson using events where a Higgs boson with mass 125 GeV decays to four leptons (ℓ = e or μ). This decay is presumed to occur via an intermediate state which contains ...
Journal article
• #### Search for pair production of up-type vector-like quarks and for four-top-quark events in final states with multiple b-jets with the ATLAS detector ﻿

(Springer Berlin Heidelberg, 2018-07-12)
A search for pair production of up-type vector-like quarks (T ) with a significant branching ratio into a top quark and either a Standard Model Higgs boson or a Z boson is presented. The same analysis is also used to search ...
