UV graviton scattering and positivity bounds from IR dispersion relations
M. Herrero-Valea, A. S. Koshelev, A. Tokareva
Scattering amplitudes mediated by graviton exchange display IR singularities in the forward limit. This obstructs standard application of positivity bounds based on twice subtracte…

Massless Positivity in Graviton Exchange
Mario Herrero-Valea, Raquel Santos-Garcia, Anna Tokareva
We formulate Positivity Bounds for scattering amplitudes including exchange of massless particles. We generalize the standard construction through dispersion relations to include t…
