The charged Higgs boson mass in the 2HDM: decoupling and CP violation

Mass range of the charged Higgs boson in the 2HDM with explicit and spontaneous CP violation is discussed. Constraints on M_H+ in the CP conserving 2HDM(II) are shown.Comment: Oct. 2007, 5 pages, 2 figures, Presented at 2007 International Linear Collider Workshop (LCWS07 and ILC07), Hamburg, Germany, 30 May - 3 Jun 200

Dark matter data and quartic self-couplings in Inert Doublet Model

We analyse the thermal evolution of the Universe in the Inert Doublet Model for three viable regions of Dark Matter mass: low, medium and high DM mass. Those three regions exhibit different behaviour in the possible types of evolution. We argue that the quartic self-couplings in IDM are significant parameters for the astrophysical analysis.Comment: Presented at XXXV International Conference of Theoretical Physics "Matter to the Deepest: Recent Developments in Physics of Fundamental Interactions," Ustron'11; 7 pages, 5 figure

IDM and not only

In this note, we discuss recent updates to a previous scan for the Inert Doublet Model, a two Higgs doublet model with a dark matter candidate. We explicitly show the inclusion of updated constraints on direct detection reduces the allowed parameter space significantly. We furthermore discuss the IDMS - an extension of the IDM with a complex singlet.Comment: 12 pages, 7 figures; Contribution to Corfu Summer Institute 2016 "School and Workshops on Elementary Particle Physics and Gravity", 31 August - 23 September, 2016, Corfu, Greec
