摘要: There is an increasing interest in nonlinear supersymmetries cosmological model building. Independently, elegant expressions for the all-tree amplitudes models with symmetries, like D3 brane Dirac-Born-Infeld-Volkov-Akulov theory, were recently discovered. Using generalized background field method we show how, general, symmetries of action, bosonic and fermionic, constrain beyond soft limits. The same identities control, example, E_{7(7)} scalar sector as well fermionic goldstino symmetries. We present a universal derivation vanishing single (bosonic or fermionic) limit. We explain why, universally, double-soft limit probes coset space algebra. also provide describing multiple-soft discuss loop corrections to N\geq 5 supergravity, brane, UV completion constrained multiplets string theory.
