Flux vacua in type IIB compactifications on orbifolds: their finiteness and minimal string coupling
Ignatios Antoniadis, Anthony Guillen, Osmin Lacombe
We perform a detailed study of (supersymmetric) moduli stabilisation in type IIB toroidal orientifolds with fluxes. We provide strong evidence towards exhaustion of the finite numb…
Cosmological perturbations from five-dimensional inflation
Ignatios Antoniadis, Jules Cunat, Anthony Guillen
It was recently proposed that five-dimensional inflation can relate the causal size of the observable universe to the present weakness of gravitational interactions by blowing up a…
More on massive gravitino scattering amplitudes and the unitarity cutoff of the new Fayet-Iliopoulos terms
Ignatios Antoniadis, Jules Cunat, Anthony Guillen
We extend the gravitino scattering amplitude computed in [1] to an arbitrary supergravity model of one chiral and one vector multiplet, in a Minkows…
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…
Ultraviolet behaviour of Higgs inflation models
Ignatios Antoniadis, Anthony Guillen, Kyriakos Tamvakis
We study the ultraviolet behaviour of Higgs inflation models above the apparent unitarity violation scale arising from the large non minimal coupling to gravity, by computing on-sh…
Fluid velocity from transverse momentum spectra
Anthony Guillen, Jean-Yves Ollitrault
We parametrize the transverse momentum distribution of outgoing hadrons in ultrarelativistic nucleus-nucleus collisions as a superposition of boosted thermal distributions. In this…
