    Description
    The SM Lagrangian without physical scalars is rewritten as the leading order of a low-energy effective theory invariant under a higher non-linearly realized symmetry Snat ⊃ SU(2)W x U(1)Y. Explicit breaking of Snat defines a hierarchy of non-standard effects dominated by small universal couplings of righthanded quarks to W. This prediction will be confronted with the recent measurement and analysis of KL(μ3) form factors by the NA48 collaboration.
