Description

I will discuss new positivity bounds at finite momentum transfer, showing that massive gravity parametrically violates these bounds unless the cutoff is within one order of magnitude of the graviton mass. These results effectively rule out massive gravity as a long distance theory consistent with a causal and unitary UV completion.
