Quest for Black Holes and Superstring Excitations in Cosmic Ray Data
Luis A. Anchordoqui, Jonathan L. Feng, Haim Goldberg +1
In this talk we discuss aspects of TeV-scale gravitational collapse to black holes and string balls and their subsequent evaporation. Special emphasis is placed on the interplay of…

BPS Structure of Argyres-Douglas Superconformal Theories
Alfred D. Shapere, Cumrun Vafa
We study geometric engineering of Argyres-Douglas superconformal theories realized by type IIB strings propagating in singular Calabi-Yau threefolds. We use this construction to co…

Curves of Marginal Stability in N=2 Super-QCD
Philip C. Argyres, Alon E. Faraggi, Alfred D. Shapere
We present a simple argument determining the shape of the curves of marginal stability in the N=2 supersymmetric SU(2) QCD with less than 4 massless flavors. The argument relies on…
