Query: Exact scaling laws for helical three-dimensional two-fluid turbulent
  plasmas   We derive exact scaling laws for a three-dimensional incompressible helical
two-fluid plasma, without the assumption of isotropy. For each ideal invariant
of the two-fluid model, i.e. the total energy, the electron helicity and the
proton helicity, we derive simple scaling laws in terms of two-point increments
correlation functions expressed in terms of the velocity field of each species
and the magnetic field. These variables are appropriate for comparison with
\textit{in-situ} measurements in the solar wind at different spatial ranges and
data from numerical simulations. Finally, with the exact scaling laws and
dimensional analysis we predict the magnetic energy and electron helicity
spectra for different ranges of scales.
