Massive gravitino scattering amplitudes and the unitarity cutoff of the new Fayet-Iliopoulos terms
Ignatios Antoniadis, Anthony Guillen, François Rondeau
We compute the gravitino scattering amplitudes at tree level in supergravity theories where supersymmetry is spontaneously broken. In the unitary gauge, the gravit…

Late time acceleration in Palatini gravity
Ignatios Antoniadis, Anthony Guillen, Kyriakos Tamvakis
We investigate the effect of the quadratic correction and non-minimal coupling on a quintessence model with an exponential potential in the Pa…

Addendum to "Ultraviolet behaviour of Higgs inflation models"
Ignatios Antoniadis, Anthony Guillen, Kyriakos Tamvakis
This article is an addendum to [1]. We extend our computation of the on-shell scattering amplitudes in an arbitrary inflaton background . Although the effective Einstein f…
