The interaction structure and cosmological relevance of mass scales in string motivated supersymmetric theories

A string motivated, N = 1 global supersymmetric, general Lagrangian is obta ined that represents an inflaton interacting with the modes of a string. Fo cus is placed on the Lagrangian's relevance to warm inflation, which is a c osmology based on dissipative dynamics. Several interaction schemes are ide ntified from the general Lagrangian that may have interesting consequences for dissipative dynamics. Distributed-mass-models, which have been shown to solve the horizon problem within a warm inflation regime, are identified i n the general Lagrangian. (C) 1999 Published by Elsevier Science B.V.
