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}.

Propagation of perturbations in non-linear spin-2 theories
Santiago E. Perez Bergliaffa
In this communication I analyze the problem of complete exceptionality of wave propagation in a class of spin 2 field theories. I show that, under the imposition of the good weak-f…

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…
