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://lecoureures.shop/product-category/ski-de-fond-homme-bottes-combi/
