Ultraviolet completion of Starobinsky inflation
Ignatios Antoniadis, Chrysoula Markou, Dimitri V. Nanopoulos
We construct an supergravity action whose bosonic part contains an arbitrary function of the scalar curvature, the so-called gravity. As in supergravity, it ca…
A Perturbatively Stable Non-Supersymmetric String Model with AdS Vacuum
Ignatios Antoniadis, Alonzo R. Diaz Avalos, Alon E. Faraggi
We present a construction of a perturbatively stable non-supersymmetric type II closed string model in four dimensions. It is based on a freely acting Scherk-Schwarz Z2-deformation…
--Inflation Derived from 4d Strings, the Role of the Dilaton, and Turning the Swampland into a Mirage
Ignatios Antoniadis, Dimitri V. Nanopoulos, Keith A. Olive
Based on a previously derived superstring model possessing a cosmological sector that mimics Starobinsky inflation, we analyze several questions addressed in the recent literature:…
SUSY at the FPF
Luis A. Anchordoqui, Ignatios Antoniadis, Karim Benakli +2
Experimental searches for supersymmetry (SUSY) are entering a new era. The failure to observe signals of sparticle production at the Large Hadron Collider (LHC) has eroded the cent…
Non-Linear Supergravity and Inflationary Cosmology
Ignatios Antoniadis, Emilian Dudas, Fotis Farakos +1
We review a series of developments concerning non-linear realizations of supersymmetry coupled to supergravity, with emphasis on some applications to inflationary Cosmology.
Through the Looking Glass into the Dark Dimension: Searching for Bulk Black Hole Dark Matter with Microlensing of X-ray Pulsars
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust +1
Primordial black holes (PBHs) hidden in the incredible bulk of the dark dimension could escape constraints from non-observation of their Hawking radiation. Since these five-dimensi…
