Classical dynamics from QFT via Stratonovich-Weyl correspondence
Alexander Ochirov, Canxin Shi
We develop a formalism for extracting relativistic classical dynamics from the S-matrix, in which massive bodies are described on phase space while massless radiation is kept in th…
Boundary to bound dictionary for generic Kerr orbits
Riccardo Gonzo, Canxin Shi
We establish a new relation between classical observables for scattering and bound orbits of a massive probe particle in a Kerr background. We find an exact representation of the H…
Classical Double Copy of Spinning Worldline Quantum Field Theory
Francesco Comberiati, Canxin Shi
We study the classical double copy of massive spinning objects in the worldline quantum field theories (WQFT) formalism. We couple the supersymmetric model to a Yan…
All-multiplicity amplitudes with four massive quarks and identical-helicity gluons
Achilleas Lazopoulos, Alexander Ochirov, Canxin Shi
We explore the on-shell recursion for tree-level scattering amplitudes with massive spinning particles. Based on the factorization structure encoded in the same way by two differen…
Classical Double Copy of Worldline Quantum Field Theory
Canxin Shi, Jan Plefka
The recently developed worldline quantum field theory (WQFT) formalism for the classical gravitational scattering of massive bodies is extended to massive, charged point particles…
Geodesics From Classical Double Copy
Riccardo Gonzo, Canxin Shi
We extend the Kerr-Schild double copy to the case of a probe particle moving in the Kerr-Schild background. In particular, we solve Wong's equations for a test color charge in a Co…
Three-Body Effective Potential in General Relativity at Second Post-Minkowskian Order and Resulting Post-Newtonian Contributions
Florian Loebbert, Jan Plefka, Canxin Shi +1
We study the Post-Minkowskian (PM) and Post-Newtonian (PN) expansions of the gravitational three-body effective potential. At order 2PM a formal result is given in terms of a diffe…
The Double Copy of Massive Scalar-QCD
Jan Plefka, Canxin Shi, Tianheng Wang
We construct the gravitational theory emerging from the double-copy of massive scalar quantum chromodynamics in general dimensions. The resulting two-form-dilaton-gravity theory co…
Breakdown of the classical double copy for the effective action of dilaton-gravity at NNLO
Jan Plefka, Canxin Shi, Jan Steinhoff +1
We demonstrate that a recently proposed classical double copy procedure to construct the effective action of two massive particles in dilaton-gravity from the analogous problem of…
