pertaining to these scattering processes, are listed in a manner which is not subject to misinterpretation and misunderstanding.

Such interactions are interesting not only in the context of simulations of the early Universe, but also in terms of the physical processes taking place in the collapsing cores of supernovae. In fact, the early papers on this subject had been stimulated by studies of the physics of supernova explosions. The neutrino-antineutrino annihilation to electron-positron pairs has been investigated for one additional reason, namely in terms of the possibility that it provides a driving mechanism for the creation of gamma-ray bursts in compact stars, i.e., in white dwarves, neutron stars, and black holes.

The goal in this paper is to create a reliable source of information with respect to these interactions, as well as to discuss a number of relevant discrepancies in the literature. One additional reason for writing this paper is that only convenient high-energy approximations are quoted in most cases for the interactions of the (anti)neutrini with the electrons and the positrons of the plasma, i.e., results obtained from calculations ignoring the rest mass of these particles; both the exact formulae and their approximated expressions at high energy are given
