Comments on magnetic black holes

We discuss aspects of magnetically charged black holes in the Standard Model. For a range of charges, we argue that the electroweak symmetry is restored in the near horizon region. The extent of this phase can be macroscopic. If Q is the integer magnetic charge, the fermions lead to order Q massless two dimensional fermions moving along the magnetic field lines. These greatly enhance Hawking radiation effects.

Automated summary

Various aspects of magnetically charged black holes in the Standard Model are discussed, with the argument that electroweak symmetry may be restored in the near horizon region for a range of charges. The presence of fermions with integer magnetic charge Q leads to massless two dimensional fermions moving along magnetic field lines, significantly enhancing Hawking radiation effects.
