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 ...
We study the effect of primordial black holes on the classical rate of nucleation of AdS regions within the standard electroweak vacuum at high temperature. We find that the energy barrier for transitions to the new vacuum, which determines the exponential suppression of the nucleation rate, can ...

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 ...
It is shown that black hole spacetimes in classical Einstein gravity are characterized by, in addition to their ADM mass M , momentum P ~ , angular momentum J ~ and boost charge K, an infinite head of supertranslation hair. The distinct black holes are distinguished by classical superrotation...
