Scientific paper

The search for high energy gamma-ray bursts from primordial black holes has continued for the past 20 years. No positive evidence for the existence of evaporating black holes has been reported. We discuss a very interesting group of gamma-ray bursts of very short time duration and an increasing hard spectrum from the published BATSE catalog. We point out that the trend, i.e., anti-correlation of hardness ratio vs. gamma-ray burst duration, would be expected if some of the short gamma-ray bursts came from black holes evaporation. A quantitative model for primordial black hole evaporation as a fireball in the context of a quark-gluon plasma model is introduced.
