Description

We study the nonlinear realization of supersymmetry in a dynamical/cosmological background in which derivative terms like kinetic terms are finite. Starting from linearly realized theories, we integrate out heavy modes without neglecting derivative terms to obtain algebraic constraints on superfields. Thanks to the supersymmetry breaking contribution by the kinetic energy, the validity of constrained superfields can be extended to various cosmological situations beyond the SUSY breaking in vacuum and inflation, including reheating, kination, the standard and kinetic axion misalignment, and cosmological relaxation.
