Freeze-in as a complementary process to freeze-out
Journal of High Energy PhysicsThere are many extensions of the Standard Model with a dark matter (DM) candidate obtained via the freeze-out mechanism. It can happen that after all experimental and theoretical constraints are taken into account, all parameter points have a relic ...

U(1)-charged Dark Matter in three-Higgs-doublet models
Journal of High Energy PhysicsWe explore three-Higgs-doublet models that may accommodate scalar Dark Matter where the stability is based on an unbroken U(1)-based symmetry, rather than the familiar ℤ2 symmetry.

Determination of Higgs-boson couplings at the LHC
, 2004 We investigate the determination of Higgs boson couplings to gauge bosons and fermions at the LHC from data on Higgs boson production and decay. We demonstrate that very mild theoretical assumptions, which are valid in general multi-Higgs doublet models,

Two-loop BSM contributions to Higgs pair production in the aligned THDM
Journal of High Energy PhysicsWe study the impact of the two-loop corrections controlled by the BSM Higgs couplings on the cross section for the production of a pair of SM-like Higgs bosons via gluon fusion in the aligned THDM.

Novel two component dark matter features in the Z 2 × Z 2 3HDM
Journal of High Energy PhysicsWe discuss the constraints and phenomenology of the ℤ 2 × ℤ 2 three Higgs doublet model (3HDM) with two inert scalars, originating two dark matter (DM) particles.
