U'(1) Neutrino Interaction at Very Low Energies
  A procedure for studying low energy neutrinos processes using hadronic
physics ideas is proposed. We describe how the neutrino-neutrino interactions
can be modelled using massive gauge theories. The mass of the gauge bosons is
created by spontaneous symmetry breaking and we show that relationship between
mass, currents and potential gauge is through vector dominance, i.e. $J_\mu =
M^2 A_\mu$. A tiny charge $U(1)$ for neutrinos is turned on for energies around
the temperature of the cosmic neutrinos background which allow the interaction
between neutrinos, above this temperature this interaction disappears. The
magnetic flux is quantized in terms of the hidden charge. We found an
approximate relation between the order parameter and neutrino condensate
$\langle{\bar \nu} \nu\rangle_{\tiny{0}}$. The relation between the neutrino
magnetic moment and hidden photons bounds are also discussed.
