SU(2) Gauge Theory with Two Fundamental Flavours: a Minimal Template for Model Building

Speaker: 
V. Drach (CERN)
Event Type: 
Seminar
Location: 
Room U2 5017 (Dept. Physics, Bicocca U.)

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.
