Abstract

Classical two-fluid description of a neutrino beam interacting with a collisionless unmagnetized plasma is presented. The streaming neutrino dynamics is described by the beam density wavelike equation which is coupled to the excited plasma wave equation in a form analogous to beam–plasma interaction. The dispersion relation obtained is analyzed for elastic and inelastic neutrino plasma interactions. It is shown that the elastic interaction is the dominant scattering process with instability growth rate strong enough to generate plasma wave.

Generation of magnetic fields in the early universe
2003, Physics Letters, Section A: General, Atomic and Solid State Physics
Nonlinear interactions between intense photon and neutrino beams and relativistically hot electron–positron–ion plasmas of the early Universe are considered. It is shown that a small fraction of ions produces large space charge electric fields in the presence of the plasma pressure gradient, relativistic photon ponderomotive force and weak nuclear driving force of neutrinos. Large space charge electric fields can separate pairs, generating the currents which are required for creating magnetic fields in plasmas. The present theory thus offers a possible clue to the origin of primordial magnetic fields in the early Universe.
Neutrino-driven wakefields in an electron-positron plasma
2002, Physics Letters, Section A: General, Atomic and Solid State Physics
A classical fluid description is used to investigate nonlinear interactions between an electron-type neutrino beam and a relativistic collisionless unmagnetized electron–positron plasma. It is shown that during the interaction a large amplitude wakefield plasma wave is generated in such a way that charged particles trapped in this wave can be accelerated to high energies. It is also shown that the symmetry among the electron and positron dynamics is broken in the presence of intense neutrino bursts.
Neutrino effective charge in a plasma
2002, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
By using dynamical techniques of the plasma physics, the neutrino effective charge in a plasma is determined here. Its value is determined by the plasma collective processes. The present theory gives a unified picture of the problem, and it also shows that the contribution of the proton motion can be very important, even if the direct weak interaction between neutrinos and protons is negligible. This results from the electron–proton correlations which are dominant in the low-frequency limit of the equivalent charge spectrum. Comparison with some of the results from the quantum field theory has been established.
