To Positivity and Beyond, where Higgs-Dilaton Inflation has never gone before

Presented by Dr. Inar TIMIRYASOV on 1 Jul 2019 from 17:40 to 18:00
Type: oral presentation
Track: Cosmological Probes


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 be compatible with a unitary, causal, local and Lorentz invariant UV completion, we derive constraints on the Wilson coefficients of the first higher order derivative operators. We show that the values allowed by the constraints are consistent with the phenomenological applications of the Higgs-Dilaton model.
