Jorge Gamboa, Richard MacKenzie, Fernando M\'endez
TL;DR
This paper calculates the exact propagation amplitude of gravitons in the strong-coupling regime, revealing that gravitons do not propagate at low temperatures due to boundary effects related to graviton components.
Contribution
It provides an exact calculation of graviton propagation amplitude in the strong-coupling regime, highlighting the absence of propagation at low temperatures.
Findings
Propagation amplitude vanishes at low temperatures
Boundary terms relate to graviton components h_x and h_+
Gravitons do not propagate in the strong-coupling, low-temperature regime
Abstract
In the context of gravity in the strong-coupling regime, the propagation amplitude of gravity coupled to relativistic particles undergoing geodesic separation is calculated exactly. Geodesic separation gives rise to boundary terms associated with the h_\times and h_+ graviton components. At low temperatures the propagation amplitude vanishes, implying no graviton propagation in this regime.
