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…
EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade
R. Alves Batista, M. A. Amin, G. Barenboim +134
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…
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…
To Positivity and Beyond, where Higgs-Dilaton Inflation has never gone before
Mario Herrero-Valea, Inar Timiryasov, Anna Tokareva
We study the consequences of (beyond) positivity of scattering amplitudes in the effective field theory description of the Higgs-Dilaton inflationary model. By requiring the EFT to…
