seminar room (basement) (Cluster building, Garching)

Alternative scenarios of electroweak spontaneous symmetry breaking should be considered in view of the recent LHC limits on the Higgs boson. Additional scalar doublets are the simplest extension of the Standard Model, compatible with electroweak precision tests. The absence of flavour-changing neutral currents requires the flavour alignment of the different Yukawa structures. The phenomenology of the Aligned Two-Higgs-Doublet Model will be discussed, stressing the presence of new sources of CP violation and its possible signatures at high-energy colliders.
