SUSY meets SMEFT: complete one-loop matching of the general MSSM
We present the complete one-loop matching of the Minimal Supersymmetric Standard Model (MSSM) onto the Standard Model Effective Field Theory (SMEFT), considering the most general case for the MSSM with conserved R-parity, which has 124 free parameters ...

Freeze-in as a complementary process to freeze-out
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
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.

Symmetries of the scalar sector of multi-Higgs-doublet models
In pursuit of the origin of the masses of particles in the Standard Model, the Brout- Englert-Higgs Mechanism predicts the existence of a scalar boson, whose discovery has been the main goal of the Large Hadron Collider. However, introducing this scalar boson does not provide the answer to all inadequacies of the Standard Model.

The first results for charged Higgs pair production associated with a neutral gauge boson at future multi-TeV muon colliders are presented within the framework of the Two-Higgs-Doublet Model (THDM).

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

Machine Learning in the 2HDM2S model for Dark Matter
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

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