“…The new gauge symmetry is broken spontaneously by the vacuum expectation value of a new complex scalar singlet. According to exploratory studies, the superweak extension of the standard model (SWSM) has the potential to explain the origin of (i) neutrino masses and mixing matrix elements [24], (ii) dark matter [25], (iii) cosmic inflation [26], (iv) stabilization of the electroweak vacuum [26] and possibly (v) leptogenesis (under investigation).…”

“…We have implemented a SARAH model file for the SWSM [24], and used it to compute the one-loop scalar self-energies and tadpoles in Feynman gauge (ξ = 1). In the following, we list explicitly the one-loop corrections to the scalar inverse-propagator matrix (A2), after some simplifications of the SARAH output.…”

We study the allowed parameter space of the scalar sector in the superweak extension of the standard model (SM). The allowed region is defined by the conditions of (i) stability of the vacuum and (ii) perturbativity up to the Planck scale, (iii) the pole mass of the Higgs boson falls into its experimentally measured range. We employ renormalization group equations and quantum corrections at two-loop accuracy. We study the dependence on the Yukawa couplings of the sterile neutrinos at selected values. We also check the exclusion limit set by the precise measurement of the mass of the W boson. Our method for constraining the parameter space using two-loop predictions can also be applied to simpler models such as the singlet scalar extension of the SM in a straightforward way.

“…[27]). This super-weak model is an economical extension of the standard model, designed to explain the origin of (i) neutrino mass and oscillations [41], (ii) dark matter (this work), (iii) cosmic inflation and stabilization of the electroweak vacuum [42], (iv) matter-antimatter asymmetry of the universe. Our goal in this paper is to constrain the parameter space of the model by assuming that N 1 is a candidate for dark matter and its abundance is just sufficient to explain the observed dark matter energy density.…”

We explore the parameter space of a U(1) extension of the standard modelalso called the super-weak model-from the point of view of explaining the observed dark matter energy density in the Universe. The new particle spectrum contains a complex scalar singlet and three right-handed neutrinos, among which the lightest one is the dark matter candidate. We explore both freeze-in and freeze-out mechanisms of dark matter production. In both cases, we find regions in the plane of the super-weak coupling vs. the mass of the new gauge boson that are not excluded by current experimental constraints. These regions are distinct and the one for freeze-out will be explored in searches for neutral gauge boson in the near future.

We explore the possibilities of dark matter production in a U(1) extension of the standard model, also called the super-weak model. The freeze-in and freeze-out mechanisms are described in detail, assuming the lightest sterile neutrino in the model as the dark matter candidate. In both scenarios we present the favoured parameter space on the plane of super-weak coupling versus the new gauge boson mass. We discuss the experimental constraints limiting each case and outline possibilities of detection.
