  • Diagnosing CP properties of the 2HDM 

    Grzadkowski, Bohdan; Øgreid, Odd Magne; Osland, Per (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 

    Grzadkowski, B.; Ogreid, Odd Magne; Osland, Per; Pukhov, A.; Poormohammadi, Mahdi (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 

    Grzadkowski, Bohdan; Øgreid, Odd Magne; Osland, Per (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 

    Basso, L.; Lipniacka, Anna; Moretti, S.; Osland, Per; Pruna, G. M.; Poormohammadi, Mahdi (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 supersymmetry in events with large missing transverse momentum, jets, and at least one tau lepton in 20 fb−1 of √s = 8 TeV proton-proton collision data with the ATLAS detector

    A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using ...
  • Supersymmetric Cascade Decays at the LHC 

    Raklev, Are R. (The University of Bergen, 2007-06-04)
