Supersymmetric Dirac-Born-Infeld axionic inflation and non-Gaussianity
Abstract An analysis is given of inflation based on a supersymmetric Dirac-Born-Infeld (DBI) action in an axionic landscape. The DBI model we discuss involves a landscape of chiral superfields with one U(1) shift symmetry which is broken by instanton type non-perturbative terms in the superpotential...
