De Sitter vacua from a D-term generated racetrack potential in hypersurface Calabi-Yau compactifications
Andreas P. Braun, Markus Rummel, Yoske Sumitomo +1
In arXiv:1407.7580 a mechanism to fix the closed string moduli in a de Sitter minimum was proposed: a D-term potential generates a linear relation between the volumes of two rigid…
Accidental Kähler Moduli Inflation
Anshuman Maharana, Markus Rummel, Yoske Sumitomo
We study a model of accidental inflation in type IIB string theory where inflation occurs near the inflection point of a small Kähler modulus. A racetrack structure helps to allevi…
De Sitter Vacua from a D-term Generated Racetrack Uplift
Markus Rummel, Yoske Sumitomo
We propose an uplift mechanism using a structure of multi-Kähler moduli dependence in the F-term potential of type IIB string theory compactifications. This mechanism requires a D-…
Probability of Vacuum Stability in Type IIB Multi-Kähler Moduli Models
Markus Rummel, Yoske Sumitomo
We study the probability that all eigenvalues of the moduli mass matrix at extremal points are positive in concrete multi-Kähler moduli models of type IIB string theory compactific…
Statistical Distribution of the Vacuum Energy Density in Racetrack Kähler Uplift Models in String Theory
Yoske Sumitomo, S. -H. Henry Tye, Sam S. C. Wong
We study a racetrack model in the presence of the leading alpha'-correction in flux compactification in Type IIB string theory, for the purpose of getting conceivable de-Sitter vac…
Preference for a Vanishingly Small Cosmological Constant in Supersymmetric Vacua in a Type IIB String Theory Model
Yoske Sumitomo, S. -H. Henry Tye
We study the probability distribution P(Λ) of the cosmological constant Λin a specific set of KKLT type models of supersymmetric IIB vacua. We show that, as we sweep through the qu…
