  The top-Higgs system, consisting of top quark (LH doublet, RH singlet), and
Higgs boson kinetic terms, with gauge fields set to zero, has an exact (modulo
total divergences) symmetry where both fermion and Higgs fields are shifted and
mixed in a supersymmetric fashion. The full Higgs-Yukawa interaction and
Higgs-potential, including additional 1/\Lambda^2 N JL-like interactions, also
has this symmetry to 0(1/\Lambda^4) up to null-operators. Thus the interaction
lagrangian can be viewed as a power series in 1/\Lambda^2. The symmetry
involves interplay of the Higgs quartic interaction with the Higgs-Yukawa
interaction and implies the relationship, \lambda = \half g^2 between the
top--Yukawa coupling, g, and Higgs quartic coupling, \lambda, at a high energy
scale \Lambda = few TeV. We interpret this to be a new physics scale. The top
quark is massless in the symmetric phase, satisfying the Nambu-Goldstone
theorem. The fermionic shift part of the current is \propto (1-H^\dagger
H/v^2), owing to the interplay of \lambda and g, and vanishes in the broken
phase. Hence the Nambu-Goldstone theorem is trivially evaded in the broken
phase and the top quark becomes heavy (it is not a Goldstino). We have
m_t=m_h,subject to radiative corrections that can in principle pull the Higgs
into concordance with experiment.
