The Effective Planck Mass and the Scale of Inflation
Ignatios Antoniadis, Subodh P. Patil
Observable quantities in cosmology are dimensionless, and therefore independent of the units in which they are measured. This is true of all physical quantities associated with the…
Ambient cosmology and spacetime singularities
Ignatios Antoniadis, Spiros Cotsakis
We present a new approach to the issues of spacetime singularities and cosmic censorship in general relativity. This is based on the idea that standard 4-dimensional spacetime is t…
String Resonances at Hadron Colliders
Luis A. Anchordoqui, Ignatios Antoniadis, De-Chang Dai +6
[Abridged] We consider extensions of the standard model based on open strings ending on D-branes. Assuming that the fundamental string mass scale M_s is in the TeV range and that t…
Enveloping branes and braneworld singularities
Ignatios Antoniadis, Spiros Cotsakis, Ifigeneia Klaoudatou
The existence of envelopes is studied for systems of differential equations in connection with the method of asymptotic splittings which allows to determine the singularity structu…
Naturalness in low-scale SUSY models and "non-linear" MSSM
I. Antoniadis, E. M. Babalic, D. M. Ghilencea
In MSSM models with various boundary conditions for the soft breaking terms (m_{soft}) and for a higgs mass of 126 GeV, there is a (minimal) electroweak fine-tuning Delta\approx 80…
The Minimal Volkov - Akulov - Starobinsky Supergravity
I. Antoniadis, E. Dudas, S. Ferrara +1
We construct a supergravity model whose scalar degrees of freedom arise from a chiral superfield and are solely a scalaron and an axion that is very heavy during the inflationary p…
