Description
We investigate a particular class of scalar field theories with higher-derivative corrections in the context of N=1 supergravity. Special attention is paid to the proper understanding of such theories within the language of effective field theory. Finally the relevance to moduli stabilization as well as inflation is discussed. Specifically the sensitivity of the inflaton potential to the presence of the higher-derivative operator is assessed.
