A bstract We analyze the tree-level potential of type IIB flux compactifications in warped Calabi-Yau orientifolds, regions weak coupling and moderately large complex structure.

A bstract The analysis of type IIB flux vacua on warped Calabi-Yau orientifolds becomes considerably involved for a large number complex structure fields. We however show that, quadratic superpotential, one can devise simplifying schemes which effectively reduce the equations down to few. This be achieved by imposing vanishing certain quanta in regime, and then choosing remaining respect symmetries underlying prepotential. One implement an algorithm find families with fixed tadpole,...

We show that one can find de Sitter critical points (saddle points) in models of flux compactification Type IIB String Theory without any uplifting terms and the presence several moduli. demonstrate this by giving explicit examples following some ideas recently presented Conlon [1], as well more generic situations where violate strong form Swampland Conjecture. stabilize complex structure dilaton with fluxes, we introduce a racetrack potential fixes K\"ahler The resultant potentials...

We report on a new class of flux vacua generically present in Calabi-Yau compactifications type-IIB string theory. At these vacua, the mass spectrum complete axiodilaton/complex structure sector is given, to leading order ${\ensuremath{\alpha}}^{\ensuremath{'}}$ and ${g}_{s}$, by simple analytic formula independent choice Calabi-Yau. provide method find construct an ensemble 17,054 solutions for hypersurface ${\mathbb{WP}}_{[1,1,1,6,9]}^{4}$, where masses axiodilaton 272 complex fields can...

A bstract This paper explores the process of vacuum decay in supersymmetric models related to flux compactifications. In particular, we describe these instabilities within Lagrangians for a single three-form multiplet. multiplet combines scalar fields, representing moduli fields four dimensions, with 3-form that influence potential via integer their associated 4-form field strength. Furthermore, using supersymmetry as guide obtain form couplings membranes act sources potentials. Adding small...

Phenomenologically interesting scalar potentials are highly atypical in generic random landscapes. We develop the mathematical techniques to generate constrained potentials, i.e. Slepian models, which can globally represent low-probability realizations of landscape. give analytical as well numerical methods construct these models for a full Gaussian field around critical inflection points. use numerically an efficient way large number minima at arbitrary heights potential and calculate their...

A bstract The large number of moduli fields arising in a generic string theory compactification makes complete computation the low energy effective infeasible. common strategy to solve this problem is consider Calabi-Yau manifolds with discrete symmetries, which effectively reduce and make truncated Effective Field Theory possible. In approach, however, couplings (e.g., masses) are left undetermined. present paper we discuss tree-level mass spectrum type-IIB flux compactifications at Large...
