The Standard Model of fundamental particles and their interactions is one of the most successful theories in physics. In particular, up to the weak scale (a few hundreds of GeV) it agrees to a great degree with a large set of experimental data. However, there are several theoretical reasons, such as the so-called "Hierarchy Problem", as well as experimental ones, such as the neutrino masses and the evidence for dark matter in the Universe, to expect that something new (particles and/or interactions) could lie at TeV scale. Hints and/or answer(s) to these fundamental questions will be provided by the Large Hadron Collider (LHC), a proton-proton collider running at high energies.The present thesis aims to explore new physics at the LHC through phenomenological studies that employ simulations and computational tools to directly link theories with experimental data. In particular, the focus is on Beyond Standard Model theories that can incorporate a quantum description of gravity, such as extra dimensional theories, Supersymmetry and yet a simplified model where the constant of Newton is scale dependent. Phenomenological analyses are performed in which graviton and gravitino emission in combination with multiple jets are investigated at hadron colliders. Inclusive samples are generated by merging matrix element with parton shower descriptions, and validated by a comparison against next-to-leading order QCD calculations. Predictions for relevant observables at the LHC and Tevatron are obtained.

L’installation des nouveaux synchrotrons de haute énergie européens ainsi que la construction de la future source à spallation européenne ouvrent des perspectives nouvelles et inédites de recherche dans le domaine des matériaux et biomatériaux. C’est tout l’enjeu de ce livre qui présente les nouveaux équipements et les évolutions les plus récentes dans les techniques d’analyses des contraintes et des textures. Rayonnement synchrotron, rayons X et neutrons au service des matériaux, fait le point sur les nouvelles thématiques abordées et présente les nouvelles générations de sources synchrotrons et sources à spallation. Dans ce livre, l’analyse de la texture cristallographique dans les matériaux est particulièrement abordée ainsi que l’intérêt de la simulation numérique pour l’analyse des contraintes. Un chapitre entier présente les résultats les plus récents dans les secteurs de l’aéronautique, du ferroviaire à grande vitesse, de la géologie ainsi que dans le domaine des biomatériaux et des matériaux nouveaux. Après une présentation générale et un historique détaillé de la mesure des déformations, les auteurs montrent l’intérêt des neutrons dans la caractérisation des matériaux ainsi que l’utilisation du rayonnement synchrotron en science des matériaux. Une présentation détaillée de la technique et des problèmes rencontrés est faite dans la détermination des contraintes mécaniques par les grands instruments.
