Bare-bones de Sitter vacua
/ Bena, Iosif (IPhT, Saclay) ; Dudas, Emilian (Ecole Polytechnique, CPHT ; CERN) ; Graña, Mariana (IPhT, Saclay) ; Lo Monaco, Gabriele (IPhT, Saclay) ; Toulikas, Dimitrios (IPhT, Saclay)
We compute the supersymmetry-breaking three-form fluxes generated by the addition of anti-D3 branes at the tip of a Klebanov-Strassler throat. These fluxes give rise to nontrivial terms in the superpotential when the throat is embedded in a flux compactification. [...]

Extra U(1), effective operators, anomalies and dark matter
/ Dudas, Emilian (Ecole Polytechnique, CPHT) ; Heurtier, Lucien (Ecole Polytechnique, CPHT) ; Mambrini, Yann (Orsay, LPT) ; Zaldivar, Bryan (Madrid, IFT)
A general analysis is performed on the dimension-six operators mixing an almost hidden Z' to the Standard Model (SM), when the Z' communicates with the SM via heavy mediators. These are fermions charged under both Z' and the SM, while all SM fermions are neutral under Z'. [...]

Strong moduli stabilization and phenomenology
/ Dudas, Emilian (Orsay, LPT ; Ecole Polytechnique, CPHT ; CERN) ; Linde, Andrei (Stanford U., Phys. Dept. ; Stanford U., ITP) ; Mambrini, Yann (Orsay, LPT) ; Mustafayev, Azar (Hawaii U. ; Minnesota U., Theor. Phys. Inst.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.)
We describe the resulting phenomenology of string theory/supergravity models with strong moduli stabilization. The KL model with F-term uplifting, is one such example. [...]

Universal contributions to scalar masses from five dimensional supergravity
/ Dudas, Emilian (CERN ; Ecole Polytechnique, CPHT) ; von Gersdorff, Gero (Ecole Polytechnique, CPHT)
We compute the effective Kahler potential for matter fields in warped compactifications, starting from five dimensional gauged supergravity, as a function of the matter fields localization. We show that truncation to zero modes is inconsistent and the tree-level exchange of the massive gravitational multiplet is needed for consistency of the four-dimensional theory. [...]

Relating the CMSSM and SUGRA models with GUT scale and Super-GUT scale Supersymmetry Breaking
/ Dudas, Emilian (Orsay, LPT ; Ecole Polytechnique, CPHT ; CERN) ; Mambrini, Yann (Orsay, LPT) ; Mustafayev, Azar (Minnesota U., Theor. Phys. Inst.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.)
While the constrained minimal supersymmetric standard model (CMSSM) with universal gaugino masses, $m_{1/2}$, scalar masses, $m_0$, and A-terms, $A_0$, defined at some high energy scale (usually taken to be the GUT scale) is motivated by general features of supergravity models, it does not carry all of the constraints imposed by minimal supergravity (mSUGRA). In particular, the CMSSM does not impose a relation between the trilinear and bilinear soft supersymmetry breaking terms, $B_0 = A_0 - m_0$, nor does it impose the relation between the soft scalar masses and the gravitino mass, $m_0 = m_{3/2}$.
