Loop induced H ± W ∓ Z vertices in the general two Higgs doublet model with CP violation
Journal of High Energy PhysicsUnderstanding symmetry of extended Higgs models helps to construct the theory beyond the standard model and gives important insights for testing these models by experiments.

Higgs and collider phenomenology of physics beyond the standard model
, 2013 This thesis explores three classes of beyond-the-Standard Model (BSM) theories: Minimal Universal Extra Dimensions (MUED), the 4D Composite Higgs Model (4DCHM) and Technicolor.

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 ...

The Little Higgs mechanism and experimental constraints on the Littlest Higgs model [PDF]
, 2013 textWe review the important features of Little Higgs models, illuminating the mechanisms that generate a naturally light Higgs field while avoiding excessive fine-tuning.

Symmetries in multi-Higgs-doublet models
, 2013 peer reviewedWe report the recent progress in understanding of symmetries which can be implemented in the scalar sector of electroweak symmetry breaking models with several Higgs doublets.

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 ...

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.

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
