Abstract

We calculate the neutrino scattering and absorption on the hot and dense neutron-star matter with hyperons under the strong magnetic field using perturbative approach. We find that the absorption cross-sections show the remarkable angular dependence: its strength is reduced in the direction parallel to the magnetic field and enhanced in the opposite direction. This variation becomes about 2.2% when the magnetic field is about 2×10¹⁷G.
