Exact Schwinger Proper Time Renormalisation
Steven Abel, Lucien Heurtier
We derive an exact version of the Schwinger Proper Time Renormalisation Group flow equation from first principles from the complete path integral, without using any perturbative ex…
Cosmological Imprints of SUSY Breaking in Models of Sgoldstinoless Non-Oscillatory Inflation
Lucien Heurtier, Ahmad Moursy, Lucien Wacquez
In supergravity, the dynamics of the sgoldstino -- superpartner of the goldstino superfield associated with the breaking of supersymmetry at low energy -- can substantially modify…
Spontaneous Freeze Out of Dark Matter
Thibaut Coudarchet, Lucien Heurtier, Hervé Partouche
We present a new paradigm for the production of dark-matter particles called the spontaneous freeze out, in which the decoupling from the thermal bath is enforced by the sudden inc…
Spontaneous dark-matter mass generation along cosmological attractors in string theory
Thibaut Coudarchet, Lucien Heurtier, Herve Partouche
We propose a new scenario for generating a relic density of non-relativistic dark matter in the context of heterotic string theory. Contrary to standard thermal freeze-out scenario…
Sgoldstino-less inflation and low energy SUSY breaking
Riccardo Argurio, Dries Coone, Lucien Heurtier +1
We assess the range of validity of sgoldstino-less inflation in a scenario of low energy supersymmetry breaking. We first analyze the consistency conditions that an effective theor…
Sneutrino driven GUT Inflation in Supergravity
Tomas E. Gonzalo, Lucien Heurtier, Ahmad Moursy
In this paper, we embed the model of flipped GUT sneutrino inflation -in a flipped SU(5) or SO(10) set up- developed by Ellis et al. in a supergravity framework. The GUT symmetry i…
