Positivity with Long-Range Interactions
B. Bellazzini, J. Berman, G. Isabella +3
We introduce infrared finite, analytic, crossing symmetric, Regge behaved, and Lorentz invariant amplitudes , labeled by the experimental energy resolut…
Completeness from Gravitational Scattering
Francesco Calisto, Clifford Cheung, Grant N. Remmen +2
We prove that symmetry in the presence of gravity implies a version of the completeness hypothesis. For a broad class of theories, we demonstrate that the existence of finitely man…
Strings from Almost Nothing
Clifford Cheung, Grant N. Remmen, Francesco Sciotti +1
We argue that string theory emerges inevitably from a few simple assumptions about physical scattering. Consistency alone requires that all tree-level four-point scattering amplitu…
(Super)Gravity from Positivity
Brando Bellazzini, Alex Pomarol, Marcello Romano +1
We investigate whether the effective theory for isolated, massive, and weakly interacting spin- particles is compatible with causality and unitarity-i.e., the positivity of sc…
