Magnetically charged black holes (MBHs) are interesting solutions of the Standard Model and general relativity. They may possess a "hairy" electroweak-symmetric corona outside the event horizon, which speeds up their Hawking radiation and leads them to become nearly extremal on short timescales. ...

universe at these high energies, of order1015GeV and above, comes predominantly from extrapolations of known physics at the electroweak scale. Measurements of the primordial density fluctuations via the abundance of primordial black holes would provide unique insights into physics at these ultra-high ...
Blackholes with mass larger than ∼ 10 5 gm appear to survive beyond the electroweak phase transition and, therefore, successfully manage to create baryon excess via X − ¯ X emissions, averting the baryon number wash-out due to sphalerons. In this scenario, we find that the ...
