DESCRIPTION:Primordial black holes (PBHs) are hypothesized to have formed 
 in the early Universe from the collapse of large primordial overdensities\
 , among other possible mechanisms. Unlike astrophysical black holes produc
 ed by stellar collapse\, PBHs could have formed with much smaller masses. 
 In particular\, PBHs with initial masses below\, or of order \,10^{15} g a
 re significantly affected by Hawking radiation\, through which they lose m
 ass by emitting particles with a quasi-thermal spectrum.\nAs these PBHs ap
 proach the end of their lifetimes\, their masses decrease dramatically whi
 le their temperatures rise to the TeV-PeV range. In this final phase\, the
 y are expected to emit extremely energetic photons\, neutrinos\, and cosmi
 c rays\, potentially providing observable signatures and offering a unique
  window into physics beyond the Standard Model.\nIn this seminar\, I will 
 review how a multimessenger approach can be used both to test the existenc
 e of PBHs and to probe extensions of the Standard Model involving new part
 icles.\n\nhttps://indico.ific.uv.es/event/8446/
