COMBINED LOCAL AND EQUILATERAL NON-GAUSSIANITIES FROM MULTIFIELD DIRAC-BORN-INFELD INFLATION

We explain the motivation and main idea of our work in Ref. 1. We present a simple model of multifield Dirac-Born-Infeld inflation whose bispectrum exhibits a linear combination of the equilateral and local shapes, which are usually considered as separate possibilities. We also point out the presence of a particularly interesting component of the primordial trispectrum.
