Beyond Discontinuities: Cosmological WFCs and the Supersymmetric Orthogonal Grassmannian
Yu-tin Huang, Chia-Kai Kuo, Yohan Liu +1
We construct an supersymmetric Grassmannian representation of tree-level wavefunction coefficients (WFCs) by combining Grassmannian representations of energy discont…

Fermionic Boundary Correlators in (EA)dS space
Wei-Ming Chen, Yu-tin Huang, Zi-Xun Huang +1
In this paper we bootstrap de Sitter wavefunction coefficients (WFCs) involving fermionic operators. Starting with a fixed total-energy pole order, we systematically impose the con…

Flat space Fermionic Wave-function coefficients
Bo-Ting Chen, Wei-Ming Chen, Yu-tin Huang +2
In this work we analyze the analytic structure of tree-level flat-space wavefunction coefficients (WFCs), with particular attention to fermionic operators, and derive cutting rules…
