Type-II Seesaw Higgs triplet productions and decays at the LHC
Journal of High Energy PhysicsThe Type-II Seesaw Model provides an attractive scenario to account for Majorana-neutrino masses. Its extended Higgs sector, if sufficiently light, can have a rich and distinctive phenomenology at the LHC while yielding automatically an essentially ...

Symmetries and observable parameters of multi-Higgs-doublet models
Physics Letters B, 1995 Abstract We investigate the symmetries of the Yukawa and the Higgs sectors in multi-Higgs-doublet standard models. We extend a method that was originally formulated for counting the observable parameters of the Yukawa sector of the standard model to multi-Higgs-doublet models.

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 ...

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,

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.

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.

The landscape of composite Higgs models
Journal of High Energy PhysicsWe classify all different composite Higgs models (CHMs) characterised by the coset space G $$ \mathcal{G} $$ / H $$ \mathcal{H} $$ of compact semi-simple Lie groups G $$ \mathcal{G} $$ and H $$ \mathcal{H} $$ involving up to 13 Nambu-Goldstone bosons ...
