Based on the properties of probability distributions of functions of random variables, we proposed earlier a simple stringy mechanism that prefers the meta-stable vacua with a small cosmological constant ?. As an illustration of this approach, we study in this paper particularly simple but non-trivial models of the K?hler uplift in the large volume flux compactification scenario in Type IIB string theory, where all parameters introduced in the model are treated either as fixed constants… 
Linking light scalar modes with a small positive cosmological constant in string theory
A bstractBased on the studies in Type IIB string theory phenomenology, we conjecture that a good fraction of the meta-stable de Sitter vacua in the cosmic stringy landscape tend to have a very small
Preference for a vanishingly small cosmological constant in supersymmetric vacua in a Type IIB string theory model
Abstract We study the probability distribution P ( Λ ) of the cosmological constant Λ in a specific set of KKLT type models of supersymmetric IIB vacua. We show that, as we sweep through the
On the distribution of stable de Sitter vacua
A bstractThe possible existence of (meta-) stable de Sitter vacua in string theory is of fundamental importance. So far, there are no fully stable solutions where all effects are under perturbative
Probability of vacuum stability in type IIB multi-Kähler moduli models
A bstractWe 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 compactifications in
Vacua and Inflation in String Theory and Supergravity
We study the connection between the early and late accelerated expansion of the universe and string theory. In Part I of this thesis, the observational degeneracy between single field models of
The string origin of SUSY flavor violation
A bstractWe argue that in large classes of string compactifications with a MSSM-like structure substantial flavor violating SUSY-breaking soft terms are generically induced. We specify to the case of
A universal tachyon in nearly no-scale de Sitter compactifications
A bstractWe investigate de Sitter solutions of N=1$$ \mathcal{N}=1 $$ supergravity with an F-term scalar potential near a no-scale Minkowski point, as they may in particular arise from flux
Microscopic Origin of Volume Modulus Inflation
High-scale string inflationary models are in well-known tension with low-energy supersymmetry. A promising solution involves models where the inflaton is the volume of the extra dimensions so that
Finding all flux vacua in an explicit example
A bstractWe explicitly construct all supersymmetric flux vacua of a particular Calabi-Yau compactification of type IIB string theory for a small number of flux carrying cycles and a given D3-brane
Why the Cosmological Constant is so Small ? A String Theory Perspective.
With no free parameter (except the string scale $M_S$), dynamical flux compactification in Type IIB string theory determines both the cosmological constant (vacuum energy density) $\Lambda$ and the


Stringy mechanism for a small cosmological constant
Based on the probability distributions of products of random variables, we propose a simple stringy mechanism that prefers the meta-stable vacua with a small cosmological constant. We state some
Model-independent properties and cosmological implications of the dilaton and moduli sectors of 4D strings
Abstract We show that if there is a realistic 4D string, the dilaton and moduli supermultiplets will generically acquire a small mass ∼ O(m 3 2 ) , providing the only vacuum-independent evidence of
Simple de Sitter solutions
We present a framework for de Sitter model building in type IIA string theory, illustrated with specific examples. We find metastable dS minima of the potential for moduli obtained from a
Large-volume flux compactifications: Moduli spectrum and D3/D7 soft supersymmetry breaking
We present an explicit calculation of the spectrum of a general class of string models, corresponding to Calabi-Yau flux compactifications with h1,2 > h1,1 > 1 with leading perturbative and
A sufficient condition for de Sitter vacua in type IIB string theory
A bstractWe derive a sufficient condition for realizing meta-stable de Sitter vacua with small positive cosmological constant within type IIB string theory flux compactifications with spontaneously
General analysis of LARGE Volume Scenarios with string loop moduli stabilisation
We study the topological conditions for general Calabi-Yaus to get a non-supersymmetric AdS exponentially large volume minimum of the scalar potential in flux compactifications of IIB string theory.
Cosmology from random multifield potentials
We consider the statistical properties of vacua and inflationary trajectories associated with a random multifield potential. Our underlying motivation is the string landscape, but our calculations
Systematics of moduli stabilisation in Calabi-Yau flux compactifications
We study the large volume limit of the scalar potential in Calabi-Yau flux compactifications of type IIB string theory. Under general circumstances there exists a limit in which the potential
Systematics of string loop corrections in type IIB Calabi-Yau flux compactifications
We study the behaviour of the string loop corrections to the N = 1 4D supergravity Kahler potential that occur in flux compactifications of IIB string theory on general Calabi-Yau three-folds. We
Stringy corrections to Kähler potentials, SUSY breaking, and the cosmological constant problem
The moduli of N = 1 compactifications of IIB string theory can be stabilized by a combination of fluxes (which freeze complex structure moduli and the dilaton) and nonperturbative superpotentials
