Accidental Inflation in the Landscape
Jose J. Blanco-Pillado, Marta Gomez-Reino, Konstantinos Metallinos
We study some aspects of fine tuning in inflationary scenarios within string theory flux compactifications and, in particular, in models of accidental inflation. We investigate the…
Kahler Moduli Inflation Revisited
Jose J. Blanco-Pillado, Duncan Buck, Edmund J. Copeland +2
We perform a detailed numerical analysis of inflationary solutions in Kahler moduli of type IIB flux compactifications. We show that there are inflationary solutions even when all…
Globally and locally supersymmetric effective theories for light fields
Leonardo Brizi, Marta Gomez-Reino, Claudio A. Scrucca
We reconsider the general question of how to characterize most efficiently the low-energy effective theory obtained by integrating out heavy modes in globally and locally supersymm…
No metastable de Sitter vacua in N=2 supergravity with only hypermultiplets
Marta Gomez-Reino, Jan Louis, Claudio A. Scrucca
We study the stability of vacua with spontaneously broken supersymmetry in N=2 supergravity theories with only hypermultiplets. Focusing on the projection of the scalar mass matrix…
Constructing de Sitter vacua in no-scale string models without uplifting
Laura Covi, Marta Gomez-Reino, Christian Gross +2
We develop a method for constructing metastable de Sitter vacua in N=1 supergravity models describing the no-scale volume moduli sector of Calabi-Yau string compactifications. We c…
Constraints on modular inflation in supergravity and string theory
Laura Covi, Marta Gomez-Reino, Christian Gross +3
We perform a general algebraic analysis on the possibility of realising slow-roll inflation in the moduli sector of string models. This problem turns out to be very closely related…
