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.

Type-II Seesaw Higgs triplet productions and decays at the LHC

Journal of High Energy Physics
The 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 ...

Freeze-in as a complementary process to freeze-out

Journal of High Energy Physics
There 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 ...

Two-loop BSM contributions to Higgs pair production in the aligned THDM

Journal of High Energy Physics
We 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.

U(1)-charged Dark Matter in three-Higgs-doublet models

Journal of High Energy Physics
We 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.

Novel two component dark matter features in the Z 2 × Z 2 3HDM

Journal of High Energy Physics
We 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.

Machine Learning in the 2HDM2S model for Dark Matter

Journal of High Energy Physics
We introduce a two real scalar singlet extension of the two Higgs doublet model. We study the vacuum structure, the bounded from below conditions, the restrictions from the oblique parameters S,T and U, as well as the unitarity constraints. We submit the
