Supertrace formulae for nonlinearly realized supersymmetry
Divyanshu Murli, Yusuke Yamada
We derive the general supertrace formula for a system with chiral superfields and one nilpotent chiral superfield in global and local supersymmetry. The nilpotent multiplet is…
Tree amplitudes from nonlinear (super)symmetries in Volkov-Akulov theory
Anna Karlsson, Hui Luo, Divyanshu Murli
The characteristics of tree level scattering amplitudes in theories with nonlinear (super)symmetries were recently proposed by Kallosh to be encoded in a simple way directly from t…
Absence of U(1) Anomalous Superamplitudes in Supergravities
Daniel Z. Freedman, Renata Kallosh, Divyanshu Murli +2
We list all potential candidates for U(1) anomalous non-local 1-loop 4-point amplitudes and higher loop UV divergences in supergravities. The relevant chiral su…
Origin of Soft Limits from Nonlinear Supersymmetry in Volkov-Akulov Theory
Renata Kallosh, Anna Karlsson, Divyanshu Murli
We apply the background field technique, recently developed for a general class of nonlinear symmetries, at tree level, to the Volkov-Akulov theory with spontaneously broken N=1 su…
Orthogonal Nilpotent Superfields from Linear Models
Renata Kallosh, Anna Karlsson, Benjamin Mosk +1
We derive supersymmetry/supergravity models with constrained orthogonal nilpotent superfields from the linear models in the formal limit where the masses of the sgoldstino, inflati…
From Linear to Non-linear Supersymmetry via Functional Integration
Renata Kallosh, Anna Karlsson, Divyanshu Murli
We derive a complete pure de Sitter supergravity action with non-linearly realized supersymmetry and its rigid limit, the Volkov-Akulov action, from the corresponding models with l…
