Bimetric Theory and Partial Masslessness with Lanczos-Lovelock Terms in Arbitrary Dimensions
S. F. Hassan, Angnis Schmidt-May, Mikael von Strauss
Ghost-free bimetric theories describe nonlinear interactions of massive and massless spin-2 fields and, hence, provide a natural framework for investigating the phenomenon of parti…
On Partially Massless Bimetric Gravity
S. F. Hassan, Angnis Schmidt-May, Mikael von Strauss
We extend the notion of the Higuchi bound and partial masslessness to ghost-free nonlinear bimetric theories. This can be achieved in a simple way by first considering linear massi…
On Consistent Theories of Massive Spin-2 Fields Coupled to Gravity
S. F. Hassan, Angnis Schmidt-May, Mikael von Strauss
We consider the issues that arise out of interpreting the ghost-free bimetric theory as a theory of a spin-2 field coupled to gravity. This requires identifying a gravitational met…
Proof of Consistency of Nonlinear Massive Gravity in the Stuckelberg Formulation
S. F. Hassan, Angnis Schmidt-May, Mikael von Strauss
We address some recent concerns about the absence of the Boulware-Deser ghost in the Stuckelberg formulation of nonlinear massive gravity. First we provide general arguments for wh…
Metric Formulation of Ghost-Free Multivielbein Theory
S. F. Hassan, A. Schmidt-May, M. von Strauss
We formulate the recently proposed ghost-free theory of multiple interacting vielbeins in terms of their corresponding metrics. This is achieved by reintroducing all local Lorentz…
