CP-violating top quark couplings at future linear $e^+e^-$ colliders / Bernreuther, Werner (RWTH Aachen U.) ; Chen, Long (RWTH Aachen U. ; Munich, Max Planck Inst.) ; García, Ignacio (Valencia U., IFIC ; CERN) ; Perello Rosello, Martin (Valencia U., IFIC) ; Poeschl, Roman (Orsay, LAL) ; Richard, Francois (Orsay, LAL) ; Ros, Eduardo (Valencia U., IFIC) ; Vos, Marcel (Valencia U., IFIC)
We study the potential of future lepton colliders to probe violation of the CP symmetry in the top quark sector. In certain extensions of the Standard Model, such as the two-Higgs-doublet model (2HDM), sizeable anomalous top quark dipole moments can arise, that may be revealed by a precise measurement of top quark pair production.

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mixing between multiple Higgs bosons or other new scalar bosons. [...]

Search for charged Higgs bosons in ATLAS / Pelikan, D (Uppsala U.)
Charged Higgs bosons are predicted in several extensions of the Standard Model, where there is more than one doublet of complex scalars in the Higgs sector, for instance Two-Higgs-Doublet Models (2HDM), which is also the case in the Minimal Supersymmetric Standard Model (MSSM). For m(H+) < m(top), the dominant production mode for charged Higgs bosons at the LHC is via the decay t -> bH+ of one of the top quarks in ttbar events. [...]

Two-Higgs-Doublet Models with CP violation / Ginzburg, Ilya F. (Sobolev IM, Novosibirsk) ; Krawczyk, Maria (CERN ; Warsaw U.) ; Osland, Per (Bergen U.)
We consider the Two-Higgs-Doublet Model and determine the range of parameters for which CP violation and Flavor Changing Neutral Current effects are naturally small. It corresponds to small values of the mass parameter m_{12}^2, describing soft (\phi_1,\phi_2) mixing in the potential. [...]
