From BCJ double copy to inflationary cosmolog
Abstract: The BCJ double copy relates the scattering amplitudes from gauge and gravity theories. One such theory corresponds to a model first developed by Volkov and Akulov to describe Goldstone fermions (associated with spontaneous supersymmetry breaking). It was later realized that the Volkov-Akulov model is equivalent to the same constrained (nilpotent) superfields appearing in the cosmological models known as alpha-attractors. In this talk I'll explore some possible applications of the double copy procedure to inflationary cosmology.
