This research project lies in the area of particle physics. The primordial purpose of particle physics is to probe and understand matter and spacetime at distances as small as possible, i.e. at very high energies. Up to now, Nature is well described by the Standard Model of Particle Physics, up to an energy scale of about 1 TeV (1018 m). However, many enigmas accompany the Standard Model, so that it seems unavoidable that new and more fundamental physics near the TeV-scale still remains to be discovered.My research project aims at contributing significantly to our understanding of Physics Beyond the Standard Model, both on the theory and the phenomenology sides. My line of formal research includes the study of higher-spin theories, renormalization flow in compact extra-dimensions, and the building of realistic theories extending the Standard Model. For the latter, I am interested in all existing ideas including supersymmetry, Grand Unification, extra-dimensions and branes, as well as in new ideas like graded gauge theories. Closer to LHC physics, I work on confronting models against the existing data, in particular by using effective Lagrangians. I am particularly focused on simulations of light-by-light scattering for the upgraded LHC, that we found to be sensitive to phenomena like a strongly-interacting dilaton, magnetic monopoles and warped KK gravitons. Finally, I also work on developing new statistical methods and tools, as I believe such tools are crucial for the upcoming LHC analysis, including Higgs precision physics. (AU)
