Neutrino interaction with strongly magnetized electron-positron plasma

A study is made of a complete set of neutrino-electron processes in a magnetized plasma. It is shown that processes involving neutrinos in the initial and final states nue(-/+) --> nue(-/+) and nu <----> nue(-)e(+) have kinematic amplification in the ultrarelativistic limit. Relatively simple expressions are obtained for the probability and average neutrino energy-momentum loss which are convenient for quantitative analysis. It is observed that the total contribution of nue processes did not depend on the chemical potential of the magnetized electron-positron plasma. (C) 2000 MAIK "Nauka/Interperiodica".
