Author(s): Michael Koehn, Jean-Luc Lehners, and Burt A. Ovrut It was recently demonstrated that, when coupled to N =1 supergravity, the Dirac-Born-Infeld (DBI) action constructed from a single chiral superfield has the property that when the higher-derivative terms become important, the potential becomes negative. Thus, DBI inflation cannot occur in its most in... [Phys. Rev. D 86, 123510] Published Fri Dec 07, 2012
