- Partially Massless Gravity

On de

Sitter space, there exists a special value for the mass of a graviton for which

the linear theory propagates 4 rather than 5 degrees of freedom. If a fully non-linear version of the theory

exists and can be coupled to known matter, it would have interesting properties

and could solve the cosmological constant problem. I will describe evidence for and obstructions

to the existence of such a theory.
