What is it about?
The Standard Model of particle physics has been very successful so far but leaves some questions open, one of them being the huge difference between the energy scales of gravitation and the three other fondamental forces. A way to solve this issue would be the addition of extra space dimensions. A possible signature probing their existence at high energy colliders is by virtual exchange of gravitons. The production would occur through gluon fusion or quark-antiquark annihilation and the decay in pairs of leptons or photons (gg/qqbar -> G -> leptons/gamma gamma). Notes, publications, theses and talks are given below.
