We report yes-go and no-go results on consistent cross-couplings for a collection of gravitons. Motivated by the search of theories where multiplets of massless spin-two fields cross-interact, we look for all the consistent deformations of a positive sum of PauliFierz actions. We also investigate the problem of deforming a (positive and negative) sum of linearized Weyl gravity actions and show ...
متن کامل0 Inconsistency of interacting , multi - graviton theories
We investigate, in any spacetime dimension ≥ 3, the problem of consistent couplings for a (finite or infinite) collection of massless, spin-2 fields described, in the free limit, by a sum of Pauli-Fierz actions. We show that there is no consistent (ghost-free) coupling, with at most two derivatives of the fields, that can mix the various “gravitons”. In other words, there are no Yang-Mills-like...

متن کاملOn multi-graviton and multi-gravitino gauge theories
This paper studies nonlinear deformations of the linear gauge theory of any number of spin-2 and spin-3/2 fields with general formal multiplication rules in place of standard Grassmann rules for manipulating the fields, in four spacetime dimensions. General possibilities for multiplication rules and coupling constants are simultaneously accommodated by regarding the set of fields equivalently a...
