Supersymmetric celestial OPEs and soft algebras from the ambitwistor string worldsheet

Using the ambitwistor string, we complete list of celestial operator product expansion (OPE) coefficients for supersymmetric theories. This uses string worldsheet conformal field theory to dynamically generate OPE maximally gauge theory, as well gravity and Einstein-Yang-Mills theories, including all helicity orientation configurations. extends previous purely bosonic results [T. Adamo et al., arXiv:2111.02279] include supersymmetry provides explicit formulas which are, best our knowledge, not in literature. We also examine how infinite dimensional soft algebras behave compared cases.
