Limits on Primordial Black Hole evaporation with the H.E.S.S. array of Cherenkov telescopes

Abstract

Data collected by the H.E.S.S. array between 2004 and 2012 have been used to search for photon bursts from primordial black hole explosions. Bursts were searched for in a 30 second time-window. The duration of the search window has been optimized to increase the burst signal while keeping the statistical background low. No evidence for a burst signal was found. Preliminary upper limits on the local rate of PBH explosions of $1.4\times 10^4{pc}^{-3}{yr}^{-1}$ have been obtained, which improve previously published limits by almost an order of magnitude
