  In this talk, we describe an effective theory for electroweak symmetry
breaking without a physical Higgs, based on a symmetry larger than the
electroweak gauge group. This symmetry forbids deviations from the Standard
Model at the leading order in the appropriate chiral expansion. Indeed, the
large symmetry allows for a consistent expansion of the effective theory in
powers of momenta and spurions. The latter are automatically present: they
define the covariant reduction from the large symmetry to the electroweak
group.
