Abstract

We consider a model where electroweak symmetry breaking is driven by technicolor dynamics with minimal particle content required for walking coupling and saturation of global anomalies. Furthermore, the model features three additional Weyl fermions singlet under technicolor interactions, two of which provide for a one-loop unification of the standard model gauge couplings. Among these extra matter fields exists a possible candidate for weakly interacting dark matter. We evaluate the relic densities and find that they are sufficient to explain the cosmological observations and avoid the experimental limits from earth-based searches. Hence, we establish a nonsupersymmetric framework where hierarchy and naturality problems are solved, coupling constant unification is achieved, and a plausible dark matter candidate exists.

Dark matter from unification

Journal Article Kainulainen, Kimmo; Tuominen, Kimmo; Virkajärvi, Jussi - Journal of Cosmology and Astroparticle Physics

We consider a minimal extension of the Standard Model (SM), which leads to unification of the SM coupling constants, breaks electroweak symmetry dynamically by a new strongly coupled sector and leads to novel dark matter candidates. In this model, the coupling constant unification requires the existence of electroweak triplet and doublet fermions singlet under QCD and new strong dynamics underlying the Higgs sector. Among these new matter fields and a new right handed neutrino, we consider the mass and mixing patterns of the neutral states. We argue for a symmetry stabilizing the lightest mass eigenstates of this sector and determinemore »« less

Minimal model for dark matter and unification

Journal Article Mahbubani, Rakhi; Senatore, Leonardo - Physical Review. D, Particles Fields

Gauge coupling unification and the success of TeV-scale weakly-interacting dark matter are usually taken as evidence of low-energy supersymmetry (SUSY). However, if we assume that the tuning of the Higgs can be explained in some unnatural way, from environmental considerations for example, SUSY is no longer a necessary component of any beyond the standard model theory. In this paper we study the minimal model with a dark matter candidate and gauge coupling unification. This consists of the standard model plus fermions with the quantum numbers of SUSY Higgsinos, and a singlet. It predicts thermal dark matter with a mass thatmore »« less

Dark matter as the signal of grand unification

Journal Article Kadastik, Mario; Kannike, Kristjan; Raidal, Martti - Physical Review. D, Particles Fields

We argue that the existence of dark matter (DM) is a possible consequence of grand unification (GUT) symmetry breaking. In GUTs like SO(10), discrete Z{sub 2} matter parity (-1){sup 3(B-L)} survives despite broken B-L, and group theory uniquely determines that the only possible Z{sub 2}-odd matter multiplets belong to representation 16. We construct the minimal nonsupersymmetric SO(10) model containing one scalar 16 for DM and study its predictions below M{sub G}. We find that electroweak symmetry breaking occurs radiatively due to DM couplings to the standard model Higgs boson. For thermal relic DM the mass range M{sub DM}{approx}O(0.1-1) TeV ismore »« less

Light composite Higgs boson from higher representations versus electroweak precision measurements: Predictions for CERN LHC

Journal Article Dietrich, Dennis; Sannino, Francesco; Tuominen, Kimmo - Physical Review. D, Particles Fields

We investigate theories in which the technifermions in higher dimensional representations of the technicolor gauge group dynamically break the electroweak symmetry of the standard model. Somewhat surprisingly, for the two-index symmetric representation of the gauge group the lowest number of techniflavors needed to render the underlying gauge theory quasiconformal is two. This is exactly one doublet of technifermions with respect to the weak interactions promoting these theories to ideal candidates of walking type technicolor models. From the point of view of the weak interactions the two techniflavor theory has a Witten anomaly, which we cure by introducing a fourth familymore »« less

Flavor unification, dark matter, proton decay, and other observable predictions with low-scale S{sub 4} symmetry

Journal Article Parida, Mina; Sahu, Pradip; Bora, Kalpana - Physical Review. D, Particles Fields

We show how gauge coupling unification is successfully implemented through nonsupersymmetric grand unified theory, SO(10)xG{sub f}(G{sub f}=S{sub 4},SO(3){sub f},SU(3){sub f}), using a low-scale flavor-symmetric model of the type SU(2){sub L}xU(1){sub Y}xSU(3){sub C}xS{sub 4} recently proposed by Hagedorn, Lindner, and Mohapatra, while assigning matter-parity discrete symmetry for the dark matter stability. For gauge coupling unification in the single-step-breaking case, we show that a color-octet fermion and a hyperchargeless weak triplet fermionic dark matter are the missing particles needed to complete its minimal supersymmetric standard model-equivalent degrees of freedom. When these are included, the model automatically predicts the nonsupersymmetric grand unification withmore »« less
