Pulse of neutrinos, E m, hits plasma->charge seperation?

Pulse of neutrinos, E>>m, hits plasma-->charge seperation?

When a large pulse of neutrinos, each with an energy much greater than the electron rest mass energy, hits some plasma does this give rise to charge separation for the plasma? Could one make a simple argument why this is true or false?

Thanks for any help.

The answer seems to be "yes", but a simple argument? I found a couple of papers that use a fluid approach, but this is beyond my pay grade. http://www.springerlink.com/content/y721025uj77krm77/

Using dynamical techniques of the plasma physics, the neutrino (antineutrino) effective charge in a magnetized dense electron–positron plasma is determined here. It shown that its value, which is determined by the plasma collective processes, depends mainly on the propagation direction of plasma waves and neutrinos against the external magnetic field direction. The direction dependence of the effective charge occurs due to the fact that the magnetic field breaks the plasma isotropy. The present theory gives a unified picture of the problem which is valid for an external magnetic field below the Landau–Schwinger critical value. Comparison with some of the results from the quantum field theory has been made. © 2004 American Institute of Physics.
