Gauged R-symmetry and its anomalies in 4D N=1 supergravity and phenomenological implications
I. Antoniadis, D. M. Ghilencea, R. Knoops
We consider a class of models with gauged U(1)_R symmetry in 4D N=1 supergravity that have, at the classical level, a metastable ground state, an infinitesimally small (tunable) po…
Deconfinement transition in SU(2) Yang-Mills theory: A two-loop study
U. Reinosa, J. Serreau, M. Tissier +1
In a recent work we have proposed a perturbative approach for the study of the phase transition of pure Yang-Mills theories at finite temperature. This is based on a simple massive…
Floating JMaRT
Guillaume Bossard, Stefanos Katmadas
We define a new partially solvable system of equations that parametrises solutions to six-dimensional N=(1,0) ungauged supergravity coupled to tensor multiplets. We obtain this sys…
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…
A semi-holographic model for heavy-ion collisions
Edmond Iancu, Ayan Mukhopadhyay
We develop a semi-holographic model for the out-of-equilibrium dynamics during the partonic stages of an ultrarelativistic heavy-ion collision. The model combines a weakly-coupled…
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…
