SUSY meets SMEFT: complete one-loop matching of the general MSSM
Journal of High Energy PhysicsWe 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
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 ...

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.

On-shelļ methods for perturbative QCD [PDF]
, 2006 We present new on-shell techniques for the calculation of colour ordered helicity amplitudes in QCD. We review the methods of on-shell recursion and the MHV rules before applying them to tree-level processes within the Standard Model.

Machine Learning in the 2HDM2S model for Dark Matter
Journal of High Energy PhysicsWe 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

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.
