We consider theories with one gauge group (SU, SO or Sp) and one scalar in a two-index representation. The renormalizable action often has accidental symmetries (such as global U(1) or unusual group parities) that lead to one or more stable states, providing Dark Matter candidates. We discuss the confined phase(s) of each theory and compute the two Higgs phases, finding no generic dualities among them. Discrete gauge symmetries can arise and accidental symmetries can be broken, possibly giving… 
Dark Matter in scalar Sp($$ \mathcal{N} $$) gauge dynamics
We consider a model with Sp dark gauge group and a scalar field in the fundamental representation, which leads to two co-stable DM candidates at the perturbative level thanks to a global U(1)
Axion quality from the (anti)symmetric of SU ( N )
: We propose two models where a U(1) Peccei-Quinn global symmetry arises accidentally and is respected up to high-dimensional operators, so that the axion solution to the strong CP problem is
Thermal squeezeout of dark matter
We carry out a detailed study of the confinement phase transition in a dark sector with a SU ( N ) gauge group and a single generation of dark heavy quark. We focus on heavy enough quarks such that
Glueballs in a thermal squeezeout model
Abstract It has been shown that a first order confinement phase transition can drastically change the relic dark matter abundance in confining dark sectors with only heavy dark quarks. We study the
Axion quality from the (anti)symmetric of SU($$ \mathcal{N} $$)
We propose two models where a U(1) Peccei-Quinn global symmetry arises accidentally and is respected up to high-dimensional operators, so that the axion solution to the strong CP problem is
Analytical relations for the bound state spectrum of gauge theories with a Brout-Englert-Higgs mechanism
We apply the method proposed by Frohlich, Morchio, and Strocchi to analyze the bound state spectrum of various gauge theories with a Brout-Englert-Higgs mechanism. These serve as building blocks for
Multi-Higgs boson probes of the dark sector
In the Higgs portal framework, cascade decays of the dark sector fields naturally produce multi-Higgs final states along with dark matter. It is common that heavier dark states couple stronger to

I discuss the implementation of the Peccei-Quinn mechanism in a minimal realization of the Pati-Salam partial unification scheme. The axion mass is shown to be related to the Pati-Salam breaking
Gravitational vector Dark Matter
A new dark sector consisting of a pure non-abelian gauge theory has no renormalizable interaction with SM particles, and can thereby realise gravitational Dark Matter (DM). Gauge interactions confine

Dark Matter from self-dual gauge/Higgs dynamics
Abstract We show that a new gauge group with one new scalar leads to automatically stable Dark Matter candidates. We consider theories where the Higgs phase is dual to the confined phase: it is

A bstractWe build models where Dark Matter candidates arise as composite states of a new confining gauge force, stable thanks to accidental symmetries. Restricting to renormalizable theories
Towards the spectrum of the SU(2) adjoint Higgs model
Scalar particles in the adjoint representation of a non-Abelian gauge theory play an important role in many scenarios beyond the standard model, especially of GUT type. For such theories manifestly

We provide a simple UV theory for a Dirac dark matter with a massless Abelian gauge boson. We introduce a single fermion transforming as the $\bf{16}$ representation in the SO(10)$'$ gauge group,

We investigate the possibility that the symmetry of asymptotically free theories whose effective scalar quartic coupling constants (in the sense of the renormalization group) take on negative values
