DESCRIPTION:Speakers: Alexandra Dobrynina ()\nAn influence of a magnetic f
 ield on beta-processes is investigated under conditions of a core-collapse
  supernova. For realistic magnetic fields reachable in astrophysical objec
 ts we obtain simple analytical expressions for reaction rates of beta-proc
 esses as well as the energy and momentum transferred from neutrinos and an
 tineutrinos to the matter. Based on the results of one-dimensional simulat
 ions of a supernova explosion\, we found that\, in the magnetic field with
  the strength $B \\sim 10^{15}$ G\, the quantities considered are modified
  by a few percents only and\, as a consequence\, the magnetic-field effect
 s can be safely neglected\, considering neutrino interaction and propagati
 on in a supernova matter. The work is supported by the Russian Science Fou
 ndation (Grant No. 18-72-10070).\n\nhttps://indico.particle.mephi.ru/event
