Hollow vortices of neutrino from Kerr black hole

Abstract

In the present paper, a novel family of neutrino fields with a hollow distribution outside a rotating black hole is developed. To analyze the hollow neutrino field which excited from the Kerr black hole a theoretical method is proposed. The neutrinos wave function from the Kerr black hole is reported as hypergeometric form. Similar to the hollow in the core of the rotating black hole, the emitted neutrinos with a dark core are reported. The emitted neutrino beams are characterized by a tube of energy and angular momentum with a singularity at the center. The tubes have a symmetric axis that coincided with the symmetric axis of the rotating black hole. The number rate, emitted power, and angular momentum of the neutrinos near the rotation axis of the black hole vanish. Furthermore, the maximum rate is taken place near the equator plane of the black hole. As the black hole is rotating, its angular momentum is transferred to the emitted neutrinos, hence the helicity of the neutrinos wave function is excited.
