  Spontaneous symmetry breaking is examined by regarding it as a phenomenon in
the eternal intermediate state due to sequential perturbations. The concept of
the relativistic many-body state is applied to this intermediate state
occurring in the collision of massless Dirac fermions. Time in the relativistic
many-body state should evolve while maintaining the direction of time in each
particle, even if the particles are viewed from any inertial frames. This
kinematical requirement leads to spontaneous symmetry breaking in the vacuum of
these states, which gives a different meaning to the results of the Higgs
model. In this vacuum, massless fermion-antifermion pairs and coherent
collection of gauge bosons condense, which determine each other's mass. When a
local excitation of the condensed gauge bosons propagates in space, a
Higgs-like boson appears. The effective coupling of this Higgs-like boson to
gauge bosons is calculated as a one-loop process. With this coupling, the total
cross section of the pair annihilation of fermion and antifermion to gauge
boson pair is calculated. Renormalizability of this model is discussed using
the inductive method. Since the Higgs Lagrangian is not assumed, the divergence
we must renormalize is only the logarithmic divergence, not the quadratic one.
