Can a Massive Graviton be a Stable Particle
- 1
Abstract
This document is based on a question asked in the Dark Side of the Universe 2010 conference in Leon, Mexico, when a researcher from India asked the author about how to obtain a stability analysis of massive gravitons. The answer to this question involves an extension of the usual Pauli_Fiertz Langrangian as written by Ortin, with non- zero graviton mass contributing to a relationship between the trace of a revised GR stress-energy tensor (assuming non- zero graviton mass), and the trace of a revised symmetric tensor times a tiny mass for a 4 dimensional graviton. The resulting analysis makes use of Visser’s treatment of a stress en-ergy tensor, with experimental applications discussed in the resulting analysis. If the square of frequency of a massive graviton is real valued and greater than zero, stability can be possibly confirmed experimentally.
