MOHANTY, Subhendra; SAHU, Sarira  and  GOSWAMI, Srubabati. Emission of electron density waves by neutrinos in a dense medium. Rev. mex. fis. [online]. 2002, vol.48, n.1, pp.43-47. ISSN 0035-001X.

We study the production of electron density waves by neutrinos propagating through a plasma. We treat this process in field theoretically as a Cherenkov emission of phonons (quanta of electron density waves) by neutrinos. The energy transferred to a supernova shock wave by phonon emission from neutrinos is a factor 2 x 10² times the corresponding energy deposited by plasmon (longitudinal photon) emission.

Keywords : Neutrino; supernova; phonon.
