From theCambridge English Corpus Instead, we shall follow here a different approach, which will eventually lead to the same kind of kinetic equation for theneutrinodistribution. From theCambridge English Corpus As shown above, the parametric instability of theneutrinofield could act as an amplifier of the direct and modified processes. From theCambridge English Corpus Cosmological neutrinos: can they contribute to molecular homochirality? From theCambridge English Corpus We see that the similarity is striking and that, again, the collectiveneutrinodynamics in a plasma strongly resembles that of the electrons. From theCambridge English Corpus If neutrinos are of sufficiently low mass, then it is expected that they probably contribute approximately the same amount. From theCambridge English Corpus The second is when the two possibleneutrinohelicity states are coupled by the electron plasma oscillations. From theCambridge English Corpus The collective coupling of neutrinos and anti-neutrinos in a dense plasma is considered. From theCambridge English Corpus The collective kinetic interaction of aneutrinodistribution with electrostatic waves propagating in a dense plasma is considered. From theCambridge English Corpus Therefore, it is important to have a clear under standing of the ideal case of a monoenergeticneutrinobeam. From theCambridge English Corpus As a final application, the case of a monoenergeticneutrinobeam and the resultingneutrino-beam-plasma instability has been considered. From theCambridge English Corpus In steady state these two symmetric reactions lead to the emission of neutrinos and anti-neutrinos in equal number s and cool down the core of the star. From theCambridge English Corpus We use the known theoretical result of the split in energy of the two helicity states of an electron in the cosmicneutrinobath due to weak charged currents6,7. From theCambridge English Corpus Here, the replacement of the photon gas by theneutrinogas leads to the appearance of similar resonant kinetic interactions with the electron plasma waves, but also to specific features.
