Dual Fields of Massive/Massless Gravitons in IR/UV Completions

TL;DR

This paper explores a holographic framework where a Higgs-like mechanism gives rise to massive and massless gravitons in different energy regimes, with potential implications for cosmology and gravitational wave observations.

Contribution

It proposes a dual-field model for gravitons in IR/UV regimes based on a holographic analogy with the BEH mechanism, suggesting new avenues for understanding gravity and cosmology.

Findings

Hypothesizes dual fields of massive gravitons in IR limit.

Suggests gravitational wave observations could test the model.

Addresses potential solutions to dark matter and dark energy issues.

Abstract

In the holographic picture, the Brout-Englert-Higgs (BEH) mechanism in d-dimensional Yang-Mills theories is conjectured to provide a Higgs-like mechanism for gravity in d+1 dimensions, resulting in massive (or massless) gravitons in IR (or UV) completions. Accordingly, one could imagine dual (magnetic-type) fields of massive gravitons in the IR (low-energy) limit that are coupled to the curl of their own energy-momentum, as well as to the rotation of matter fields on large scales. This hypothesis, which might solve cosmological issues currently ascribed to dark matter and dark energy, needs to be examined by the future Laser Interferometer Space Antenna (LISA) mission using observations of gravitational waves emitted from extragalactic sources.
