F-Term Hybrid Inflation, Metastable Cosmic Strings and Low Reheating in View of ACT
C. Pallis
We consider the formation of metastable cosmic strings in a left-right unified theory. The produced monopoles are diluted by a stage of F-term hybrid inflation (FHI) which is reali…
F-Term Hybrid Inflation and SUSY Breaking
C. Pallis
We consider F-term hybrid inflation and supersymmetry breaking in the context of a model which largely respects a global U(1) R symmetry. The Kaehler potential parameterizes the Ka…
High-Scale SUSY from Sgoldstino Inflation
C. Pallis
We review a number of unimodular no-scale supergravity models with F-term SUSY breaking which support technically natural de Sitter vacua. A variant of these models develops a stag…
Starobinsky Inflation with T-Model Kaehler Geometries
C. Pallis
We present novel implementations of Starobisky-like inflation within Supergravity adopting Kaehler potentials for the inflaton which parameterize hyperbolic geometries known from t…
T-Model Higgs Inflation and Metastable Cosmic Strings
C. Pallis
We present the formation of metastable cosmic strings (CSs) in the context of a supersymmetric (SUSY) left-right model. The SU(2)R symmetry breaking occurs during a stage of T-mode…
