Abstract We study two-dimensional celestial conformal field theory describing four- dimensional N $$ \mathcal{N} $$ =1 supergravity/Yang-Mills systems and show that the underlying symmetry is a supersymmetric generalization of BMS symmetry. We construct fermionic conformal primary wave functions and show how they are related via supersymmetry to their bosonic partners. We use soft and... https://www.roneverhart.com/Craggy-Range-Sauvignon-Blanc-Te-Muna-Road-Vineyard-Martinborough-2022/
