Исследуется эволюция потока нейтрино, проходящего через конденсированное вещество и интенсивное магнитное поле. В качестве примера интенсивного магнитного поля рассматривается магнитное поле спаренных солнечных пятен, которые являются источниками солнечных вспышек. Предполагается, что нейтрино обладает дипольным магнитным и анапольным моментами, в то время как магнитное поле является скрученным, носит непотенциальный характер и его напряженность может быть ≥105 Гс. Проблема исследуется в рамках трех нейтринных поколений. Изучаются возможные резонансные переходы в нейтринном потоке.

In this paper, we investigate the evolution of the neutrino flux propagating through dense matter and an intensive magnetic field. As an example, the magnetic field of the coupled sunspots being the sources of solar flares is considered. We assume that neutrinos possess dipole magnetic and anapole moments while the magnetic field is twisting and nonpotential, and its strength may be ≥105 Gs. The problem is investigated within three neutrino generations. Possible resonance conversions inside the neutrino flux are studied.
