Massive Gravity is not Positive
Brando Bellazzini, Giulia Isabella, Sara Ricossa +1
We derive new positivity bounds at finite momentum transfer, assuming a large separation between the mass of the lightest particle in the effective theory and the mass gap …
Explaining Nonlinearities in Black Hole Ringdowns from Symmetries
Alex Kehagias, Davide Perrone, Antonio Riotto +1
It has been recently pointed out that nonlinear effects are necessary to model the ringdown stage of the gravitational waveform produced by the merger of two black holes giving ris…
Cornering Large- QCD with Positivity Bounds
Clara Fernandez, Alex Pomarol, Francesco Riva +1
The simple analytic structure of meson scattering amplitudes in the large- limit, combined with positivity of the spectral density, provides precise predictions on low-energy…
Towards a nonperturbative construction of the -matrix
Brian Henning, Hitoshi Murayama, Francesco Riva +2
We present a nonperturbative recipe for directly computing the -matrix in strongly-coupled QFTs. The method makes use of spectral data obtained in a Hamiltonian framework and ca…
Truncation, validity, uncertainties
Ilaria Brivio, Sally Dawson, Jorge de Blas +19
The truncation of the standard-model effective field theory, its validity and the associated uncertainties have been discussed in meetings of the LHC EFT WG. Proposals were made by…
The IR-Side of Positivity Bounds
Brando Bellazzini, Marc Riembau, Francesco Riva
We show how calculable IR loop effects impact positivity bounds in Effective Field Theories with causal and unitary UV completions. We identify infrared singularities which appear…
