Non-minimal Higgs inflation and non-thermal leptogenesis in a supersymmetric Pati-Salam model
Pallis, Constantinos; Toumbas, Nicolaos K. (2011)We consider a supersymmetric (SUSY) Grand Unified Theory (GUT) based on the gauge group G PS = SU(4) C × SU(2) L × SU(2) R, which incorporates non-minimal chaotic inflation, driven by a quartic potential associated with ...

Non-minimal sneutrino inflation, Peccei-Quinn phase transition and non-thermal leptogenesis
Pallis, Constantinos; Toumbas, Nicolaos K. (2011)We consider a phenomenological extension of the minimal supersymmetric standard model which incorporates non-minimal chaotic inflation, driven by a quartic potential associated with the lightest right-handed sneutrino. ...

Starobinsky Inflation: From Non-SUSY to SUGRA Realizations
Pallis, Constantinos; Toumbas, Nicolaos K. (2017)We review the realization of Starobinsky-type inflation within induced-gravity supersymmetric (SUSY) and non-SUSY models. In both cases, inflation is in agreement with the current data and can be attained for sub-Planckian ...

Starobinsky-type inflation with products of Kähler manifolds
Pallis, Constantinos; Toumbas, Nicolaos K. (2016)We present a novel realization of Starobinsky-type inflation within Supergravity using two chiral superfields. The proposed superpotential is inspired by induced-gravity models. The Kähler potential contains two logarithmic ...
