Classical double copy of spinning worldline quantum field theory

A bstract We study the classical double copy of massive spinning objects in worldline quantum field theories (WQFT) formalism. couple $$ \mathcal{N} N = 1 supersymmetric model to a Yang-Mills background describe propagation spin-half particle interacting with gluons. At level, this captures physical effects up linear order spin. propose relation map spin tensors gravitation side. Enforcing R-symmetry and supersymmetry (SUSY) on integrands, we find that gravitational theory is 2 coupled dilaton-gravity (DG). check prescription for eikonal phase next-to-leading radiation at leading coupling constants, finding Grassmann nature tensor WQFT plays crucial role full agreement direct calculation model. show how deform SUSY charges free include DG. Since constraints algebra first class, can be quantized, describing vector DG, literature. In addition, investigate without preserving R-symmetry, B-field also couples worldline.
