High Temperature Matter and Gamma Rays and Neutrinos from Microscopic Black Holes

The relativistic viscous fluid equations describing the outflow of high temperature matter created via Hawking radiation from microscopic black holes are solved numerically for a realistic equation of state. The focus is on black holes with initial temperatures greater than 100 GeV, masses less than 108 kg, and lifetimes less than 6 days. The spectra of photons and neutrinos are calculated for energies between 1 GeV and the Planck energy. The most promising route for their observation is to search for point sources emitting gamma rays or neutrinos of ever-increasing energy. If observed, the data might elucidate new physics at energy scales well above that accessible to terrestrial accelerators.
