GIMPs from Extra Dimensions
Martin Holthausen, Ryo Takahashi
TL;DR
This paper presents a five-dimensional scalar field model with boundary conditions that realize the Froggatt-Nielsen mechanism, resulting in a gravitationally interacting dark matter candidate called GIMP.
Contribution
It introduces a novel five-dimensional setup with boundary conditions that suppress couplings to standard model particles while implementing the FN mechanism.
Findings
Scalar field acts as a GIMP candidate for dark matter.
Couplings to standard model particles are effectively vanishing.
The model successfully reproduces the FN mechanism in extra dimensions.
Abstract
We study a scalar field theory in a flat five-dimensional setup, where a scalar field lives in a bulk with a Dirichlet boundary condition, and give an implementation of this setup to the Froggatt- Nielsen (FN) mechanism. It is shown that all couplings of physical field of the scalar with the all brane localized standard model particles are vanishing while realizing the usual FN mechanism. This setup gives the scalar a role as an only Gravitationally Interacting Massive Particle (GIMP), which is a candidate for dark matter.
