We resume the state of the art of heterotic string model building, focussing on the realistic models recently obtained by compactifications of the extra dimensions on orbifolds, i.e. on
singular internal spaces.
After this, we show how to resolve the orbifold singularities and re-obtain the models as smooth compactifications of the heterotic string.
In this way, we provide a description of...

I will talk about a KKLT-like model in whixh the uplift to a Minkowski vacuum is provided by a Fayet-Iliopoulos sector. The modulus contribution to supersymmetry breaking is larger than in the models already present in the literature and a new mixed gauge-gravity mediation appears in some explicit examples. This provides an original phenomenology in principle testable at LHC.

Nous avons étudié le problème de la détection indirecte de matière noire par le biais des positrons. Grâce à de nouvelles méthodes de résolution des équations décrivant leur propagation, nous avons été en mesure d'évaluer l'incertitude qui affecte le flux des positrons cosmiques primaires et qui est dûe à notre méconnaissance des paramètres de propagation. Les flux que nous avons calculés...

At existing and future hadron colliders Higgs boson production
via gluon gluon fusion is one of the dominant Higgs production
processes. The (large) QCD corrections have been calculated at NLO and
recently at NNLO (in the heavy top quark limit). So far the NLO SUSY-QCD
corrections are only known in the heavy squark limit which is reliable
for large squark masses. We have calculated the...
