Dark matter and neutrino masses from a scale-invariant multi-Higgs portal
We consider a classically scale invariant version of the Standard Model, extended by an extra dark SU(2)X gauge group. Apart from the dark gauge bosons and a dark scalar doublet which is coupled to
Light dark matter, naturalness, and the radiative origin of the electroweak scale
A bstractWe study classically scale invariant models in which the Standard Model Higgs mass term is replaced in the Lagrangian by a Higgs portal coupling to a complex scalar field of a dark sector.
Conformal vector dark matter and strongly first-order electroweak phase transition
A bstractWe study a conformal version of the Standard Model (SM), which apart from SM sector, containing a UD(1) dark sector with a vector dark matter candidate and a scalar field (scalon). In this
Conformal invariance and singlet fermionic dark matter
We study a classically scale-invariant model with an electroweak singlet complex scalar mediator together with an anomaly free set of two fermionic dark matters. We introduce $U(1)_X$ gauge symmetry
Scale and electroweak first-order phase transitions
We consider phase transitions in the standard model (SM) without the Higgs mass term, which is coupled through a Higgs portal term to an SM singlet, classically scale-invariant gauge sector with SM

Stable mass hierarchies and dark matter from hidden sectors in the scale-invariant standard model
Scale invariance may be a classical symmetry which is broken radiatively. This provides a simple way to stabilize the scale of electroweak symmetry breaking against radiative corrections. But for
Constraints on Scalar Phantoms
We update the constraints on the minimal model of dark matter, where a stable real scalar field is added to the standard model Lagrangian with a renormalizable coupling to the Higgs field. Once we
Scale invariant extension of the standard model with a strongly interacting hidden sector.
TLDR
A scale invariant extension of the standard model with a new QCD-like strong interaction in the hidden sector that could be the cold dark matter (CDM) and study collider phenomenology, relic density, and direct detection rates of the CDM of this model.
A Two-Singlet Model for Light Cold Dark Matter
We extend the standard model by adding two gauge-singlet Z{sub 2}-symmetric scalar fields that interact with visible matter only through the Higgs particle. One is a stable dark matter WIMP, and the
