Vector Portal Pseudo-Goldstone Dark Matter

  title={Vector Portal Pseudo-Goldstone Dark Matter},
  author={Ian Chaffey},
We present a model of pseudo-Goldstone dark matter that interacts through a light vector mediator based on a spontaneously broken su(2) dark sector. The dark matter mass is induced by the explicit breaking of the dark su(2) symmetry. A residual global u(1) symmetry prevents dark matter decay. The behavior of this model is studied under the assumption that the observed dark matter relic abundance is due to thermal freeze-out. We consider selfinteraction targets for small scale structure… Expand

Vector self-interacting dark matter
We present a model of vector dark matter that interacts through a low-mass vector mediator based on the Higgsing of an SU(2) dark sector. The dark matter is charged under a U(1) gauge symmetry. EvenExpand
Cancellation Mechanism for Dark-Matter-Nucleon Interaction.
This work shows that the direct DM detection cross section vanishes at the tree level and zero momentum transfer due to a cancellation by virtue of a softly broken symmetry is operative for any mediator masses. Expand
Pseudo-Nambu-Goldstone dark matter: Examples of vanishing direct detection cross section
We consider cases where the dark matter-nucleon interaction is naturally suppressed. We explicitly show that by extending the standard model scalar sector by a number of singlets, can lead to aExpand
Self-Interacting Dark Matter
Spergel and Steinhardt have recently proposed the concept of dark matter with strong self-interactions as a means to address numerous discrepancies between observations of dark matter halos onExpand
Hidden charged dark matter
Can dark matter be stabilized by charge conservation, just as the electron is in the standard model? We examine the possibility that dark matter is hidden, that is, neutral under all standard modelExpand
Singlet-Doublet Dark Matter
In light of recent data from direct detection experiments and the Large Hadron Collider, we explore models of dark matter in which an SU(2){sub L} doublet is mixed with a Standard Model singlet. WeExpand
Complex Singlet Extension of the Standard Model
We analyze a simple extension of the standard model (SM) obtained by adding a complex singlet to the scalar sector (cxSM). We show that the cxSM can contain one or two viable cold dark matterExpand
The four basic ways of creating dark matter through a portal
We consider the possibility that along the thermal history of the Universe, dark matter (DM) would have been created from Standard Model particles, either through a kinetic mixing portal to an extraExpand
Production Regimes for Self-Interacting Dark Matter
In the context of Self-Interacting Dark Matter as a solution for the small-scale structure problems, we consider the possibility that Dark Matter could have been produced without being in thermalExpand
Making dark matter out of light: Freeze-in from plasma effects
Dark matter (DM) could couple to particles in the Standard Model (SM) through a light vector mediator. In the limit of small coupling, this portal could be responsible for producing the observed DMExpand
