Query: Observational Characteristics of the Final Stages of Evaporating
  Primordial Black Holes   Many early universe theories predict the creation of Primordial Black Holes
(PBHs). The PBHs could have masses ranging from the Planck mass to 10^5 solar
masses or higher depending on the formation scenario. Hawking showed that any
Black Hole (BH) has a temperature which is inversely proportional to its mass.
Hence a sufficiently small BH will thermodynamically radiate particles at an
ever-increasing rate, continually decreasing its mass and raising its
temperature. The final moments of this evaporation phase should be explosive.
In this work, we investigate the final few seconds of the BH burst using the
Standard Model of particle physics and calculate the energy dependent burst
time profiles in the GeV/TeV range. We use the HAWC (High Altitude Water
Cherenkov) observatory as a case study and calculate PBH burst light curves
which would be observed by HAWC.
