UHE neutrino damping in a thermal gas of relic neutrinos
J. C. D'Olivo, L. Nellen, S. Sahu +1
We present a calculation of the damping of an ultra-energetic (UHE) cosmic neutrino travelling through the thermal gas of relic neutrinos, using the formalism of finite-temperature…
Emission of electron density waves by neutrinos in a dense medium
Subhendra Mohanty, Sarira Sahu, Srubabati Goswami
We study the production of electron density waves by neutrinos propagating through a plasma. We treat this process in field theoretically as a Cerenkov emission of phonons (quanta…
Neutrino helicity flip by Cerenkov emission and absorption of plasmons in supernova
Subhendra Mohanty, Sarira Sahu
We show that in a supernova core the longitudinal photon (plasmon) has a space-like dispersion and Cerenkov absorption and emission of such photons is kinematically allowed. If the…
A New Type of Resonant Neutrino Conversions Induced by Magnetic Fields
S. Sahu, V. B. Semikoz, J. W. F. Valle
We consider resonant neutrino conversions in magnetised matter, such as a degenerate electron gas. We show how magnetisation effects caused by axial vector interactions of neutrino…
