Constraining the Dark 2HDM
Maria Krawczyk, Dorota Sokolowska
The Dark 2HDM (called also the Inert Doublet Model) is the version of the Two-Higgs-Doublet Model with an exact symmetry. It contains the SM-like Higgs boson and dark sca…
Constraints on the Higgs Sector from Processes Involving Photons
Maria Krawczyk
The Higgs sector of the Standard Model and of the Two Higgs Doublet Extensions of SM, MSSM and the general 2HDM, can be tested in processes involving photons. A short review of the…
Diphoton rate in the Inert Doublet Model with a 125 GeV Higgs boson
Bogumila Swiezewska, Maria Krawczyk
An improved analysis of the diphoton decay rate of the Higgs boson in the Inert Doublet Model is presented together with critical discussion of the results existing in the literatu…
Two-Higgs-doublet models and the Yukawa process at LEP1
Jan Kalinowski, Maria Krawczyk
We investigate the production of Higgs bosons via the Yukawa process $Z\ra f\bar{f} \ra f\bar{f} A/h $ taking into account QCD corrections and fermion mass effects. We estima…
Light Neutral Higgs Bosons at the Low Energy Collider
Debajyoti Choudhury, Maria Krawczyk
A light neutral Higgs boson in the framework of the general two Higgs doublet model (2HDM) is not excluded by existing data. We point out that it can be looked for at the proposed…
Process Z->h(A)+gamma in the Two Higgs Doublet Model and the Experimental Constraints from LEP
Maria Krawczyk, Jan Zochowski, Peter Mattig
The one-loop branching ratios for the process Z->h(A)+gamma are calculated in the general Two Higgs Doublet Model (Model II) taking into account existing constraints on the model p…
