Pair production of small black holes in heterotic string theories

Regular Seminar Massimo Bianchi (Rome Tor Vergata)

14:00 QMW
room E303 Queens Building

After reviewing how small BPS black holes with two charges can be described in perturbative Heterotic strings, we compute the cross section for their pair production at tree level and analyze angular and energy distributions. We consider both toroidal compactifications and FHSV orbifold model, and comment on scenari with large extra dimensions. Finally we briefly discuss how to extend our results to non-BPS, non-extremal and rotating BH's.
