Small cosmological constants in string theory

M Demirtas, M Kim, L McAllister, J Moritz… - Journal of High Energy …, 2021 - Springer
A bstract We construct supersymmetric AdS 4 vacua of type IIB string theory in
compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. We first find explicit …

Scale‐Separated AdS3 Vacua from G2‐Orientifolds Using Bispinors

V Van Hemelryck - Fortschritte der Physik, 2022 - Wiley Online Library
In this paper, minimal supersymmetric AdS3 solutions on G2‐orientifolds of type IIA and IIB
supergravity are studied. These are obtained by techniques of the bispinor formalism. A …

D-instantons in Type IIA string theory on Calabi-Yau threefolds

S Alexandrov, A Sen, B Stefański - Journal of High Energy Physics, 2021 - Springer
A bstract Type IIA string theory compactified on a Calabi-Yau threefold has a hypermultiplet
moduli space whose metric is known to receive non-perturbative corrections from Euclidean …

Mass Hierarchies and Quantum Gravity Constraints in DKMM‐refined KKLT

R Blumenhagen, A Gligovic… - Fortschritte der Physik, 2023 - Wiley Online Library
We carefully revisit the mass hierarchies for the KKLT scenario with an uplift term from an
anti D3‐brane in a strongly warped throat. First, we derive the bound resulting from what is …

On the Search for Low W0

I Broeckel, M Cicoli, A Maharana, K Singh… - Fortschritte der …, 2022 - Wiley Online Library
The magnitude of the vacuum expectation value of the Gukov‐Vafa‐Witten superpotential| W
0| |W_0| plays a central role in the phenomenology of type IIB flux compactifications. Recent …

Flux vacua with approximate flat directions

M Cicoli, M Licheri, R Mahanta, A Maharana - Journal of High Energy …, 2022 - Springer
A bstract We present a novel method to obtain type IIB flux vacua with flat directions at tree
level. We perform appropriate choices of flux quanta that induce relations between the flux …

Analytic periods via twisted symmetric squares

R Álvarez-García, L Schlechter - Journal of High Energy Physics, 2022 - Springer
A bstract We study the symmetric square of Picard-Fuchs operators of genus one curves and
the thereby induced generalized Clausen identities. This allows the computation of analytic …

Moduli Stabilisation and the Statistics of Low-Energy Physics in the String Landscape

I Broeckel - 2022 - amsdottorato.unibo.it
In this thesis we present a detailed analysis of the statistical properties of the type IIB flux
landscape of string theory. We focus primarily on models constructed via the Large Volume …

[图书][B] Probability Distributions of the Scalar Potential

C Mathews - 2022 - search.proquest.com
In the study of cosmological inflation, string theory and supersymmetry have motivated a
wide range of possible inflationary models. These models can be parameterized by a scalar …
