DESCRIPTION:Speakers: DEGANG WANG ()\nWe study neutrino spin and spin-flav
 or oscillations in spatially inhomogeneous multipolar magnetic fields of r
 ealistic astrophysical objects. Starting from the general neutrino electro
 magnetic interaction Hamiltonian\, we derive the effective interaction Ham
 iltonian for an arbitrarily moving neutrino in a multipolar magnetic field
  expressed in spherical coordinates. An exact analytic expression for the 
 geometric phase arising from the spatial inhomogeneity of the magnetic fie
 ld is obtained. For the particular cases of neutrino propagation inside th
 e astrophysical object along radial direction\, the resonance conditions a
 nd adiabaticity parameters for spin-flip transitions are analyzed in core-
 collapse supernovae\, using realistic magnetic field models and matter den
 sity profiles.\n\nhttps://indico.particle.mephi.ru/event/626/contributions
