Post Inflationary Behaviour of String Moduli
Andre Lukas, Alexander Niemeyer, Masahiro Yamaguchi
We analyze the behaviour of moduli fields in string effective models between the end of inflation and reheating. The effective moduli potential during this era is derived for a cla…
Gaugino Condensation and the Vacuum Expectation Value of the Dilaton
A. Niemeyer, H. P. Nilles
The mechanism of gaugino condensation has emerged as a prime candidate for supersymmetry breakdown in low energy effective supergravity (string) models. One of the open questions i…
Gaugino Condensation, S-Duality and Supersymmetry Breaking in Supergravity Models
Z. Lalak, A. Niemeyer, H. P. Nilles
The status of the gaugino condensation as the source of supersymmetry breaking is reexamined. It is argued that one cannot have stable minima with broken supersymmetry in models wh…
S-Dual Gaugino Condensation and Supersymmetry Breaking
Z. Lalak, A. Niemeyer, H. P. Nilles
The principle of S-duality is used to incorporate gaugino condensates into effective supergravity (superstring) Lagrangians. We discuss two implementations of S-duality which diffe…
