Vincent Drach-CERN: After a general introduction arguing that strongly interacting theories offer theoretically appealing solutions to some puzzles raised by the Standard Model (SM) of particle physics I will present a simple model based on an SU(2) gauge theory with two flavours. I will show that it can be used to provide a mechanism  of dynamical electroweak symmetry breaking or/and to provide an UV completion for a composite pseudo- Goldstone Higgs model. I will then  argue that lattice calculation of the strong sector alone can provide useful constraints on the effective low energy description. I will then present the  lattice results and discuss, in light of them, the expected signatures at the Large Hadron Collider.
