摘要：
The azimuthal and axial magnetic fields generated by the Laguerre-Gaussian neutrino beam in plasma are considered for the first time in this work. The generation of self-consistent azimuthal and axial magnetic fields by Ampere's law is a powerful mechanism that could be responsible for the supernovae magnetic fields. The neutrino beam with a doughnut shape profile is a better choice than a Gaussian profile to form and propagate jets. The azimuthal and axial magnetic fields generated by hollow neutrino beams can explain the formation and propagation of the jets. This result may be relevant to the understanding of the origin of magnetic fields and the acceleration of jets in astrophysics.
