Neutrino production of electron–positron pairs in a moderately strong magnetic field

Neutrino production of electron–positron pairs via the processes v v ¯ → e − e + and ν → νe − e + in a moderately strong magnetic field is investigated. Under these conditions electrons and positrons can be produced in the states corresponding to excited Landau levels. The results can be used for calculating the efficiency of the electron–positron plasma production by neutrinos in the conditions of the accretion disk around a Kerr black hole.
