Reply to "Acausality of Massive Charged Spin 2 Fields"
M. Novello, S. E. Perez Bergliaffa, R. P. Neves
We show that, contrary to the claim in hep-th/0304050, the propagation of a spin-2 field in an electromagnetic background is {\em causal}.
Causality and charged spin-2 fields in an electromagnetic background
M. Novello, S. E. Perez Bergliaffa, R. P. Neves
We show that, contrary to common belief, the propagation of a spin-2 field in an electromagnetic background is {\em causal}. The proof will be given in the Fierz formalism which, a…
The mass of the graviton and the cosmological constant
M. Novello, R. P. Neves
We show that the graviton acquires a mass in a de Sitter background given by This is precisely the fine-tuning value required for the perturbed gravitational f…
Spin-2 field theory in curved spacetime
M. Novello, R. P. Neves
We present a new formulation to deal with the consistency problem of a massive spin-2 field in a curved spacetime. Using Fierz variables to represent the spin-2 field, we show how…
