SPIN ASYMMETRIES IN PROCESSES OF ELECTRON-POSITRON PAIRS PRODUCTION BY NEUTRINOS IN SUPERSTRONGLY MAGNETIZED STARS

Abstract

We have calculated the energy transferred by the neutrinos to the unit volume of the
superstrongly magnetized stellar medium per unit time at the expense of the processes n i ®n ie-e+
with allowance for the longitudinal and transverse polarizations of the spins of the produced
positrons and electrons. We have also determined the spin asymmetries arising in these processes
and shown the astrophysical applications of the obtained results for supernova explosions.
