Dark matter (DM) without a matter asymmetry is studied in the context of Twin Higgs (TH) theories in which the LHC naturalness problem is addressed. These possess a twin sector related to the Standard Model (SM) by a (broken) $\mathbb{Z}_2$ symmetry, and interacting with the SM via a specific Higgs portal. We focus on the minimal realisation of the TH mechanism, the Fraternal Twin Higgs, with only a single generation of twin quarks and leptons, and $SU(3)'\times SU(2)'$ gauge group. We show…

Reconciling large- and small-scale structure in Twin Higgs models
A bstractWe study possible extensions of the Twin Higgs model that solve the Hierarchy problem and simultaneously address problems of the large- and small-scale structures of the Universe. Besides
Twin Higgs portal dark matter
Many minimal models of dark matter (DM) or canonical solutions to the hierarchy problem are either excluded or severely constrained by LHC and direct detection null results. In particular, Higgs
Charged Dark Matter in Supersymmetric Twin Higgs models
Supersymmetric Twin Higgs models ameliorate the fine-tuning of the electroweak scale originating from the heavy scalar top partners required by the non-discovery of them at the Large Hadron Collider.
Freezing-in twin dark matter
The mirror twin Higgs (MTH) addresses the little hierarchy problem by relating every Standard Model (SM) particle to a twin copy, but is in tension with cosmological bounds on light degrees of
A Tale of Two Twin Higgses: Addressing Little Hierarchy in Natural 2HDM Framework
In original twin Higgs model, vacuum misalignment between electroweak and new physics scales is realized by adding explicit $\mathbb{Z}_2$ breaking term. Introducing additional twin Higgs could
A minimal model for neutral naturalness and pseudo-Nambu-Goldstone dark matter
We outline a scenario where both the Higgs and a complex scalar dark matter candidate arise as the pseudo-Nambu-Goldstone bosons of breaking a global SO(7) symmetry to SO(6). The novelty of our
Natural Twin Neutralino Dark Matter.
This work investigates the possibility that a twin binolike state is the lightest supersymmetric particle and finds that its freeze-out abundance can explain the observed dark matter abundance without fine-tuning the mass spectrum of the theory.
Exotic quarks in Twin Higgs models
A bstractThe Twin Higgs model provides a natural theory for the electroweak symmetry breaking without the need of new particles carrying the standard model gauge charges below a few TeV. In the low
Gamma-rays from dark showers with twin Higgs models
A bstractWe consider a twin WIMP scenario whose twin sector contains a full dark copy of the SM hadrons, where the lightest twin particles are twin pions. By analogy to the standard WIMP paradigm,
Discovering the twin Higgs boson with displaced decays
The twin Higgs mechanism keeps the scalar sector of the Standard Model (SM) natural while remaining consistent with the nonobservation of new colored particles at the Large Hadron Collider (LHC). In


I and i
There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
