Temperature Instabilities inN = 4 Strings
Jean-Pierre Derendinger · Fortschritte der Physik · 2000
An effective supergravity description of all instabilities of N4 = 4 superstrings is derived. The construction is based on the N4 = 4 BPS mass formula at finite temperature and uses the properties of N4 = 4 gauged supergravity. It provides the boundaries of the various thermal phases in the non-perturbative moduli space. It also draws a precise picture of the dynamics in the high-temperature heterotic phase. This brief contribution summarizes results obtained in collaboration with I. Antoniadis and C. Kounnas.
