Universality in Relativistic Spinning Particle Models
Joon-Hwi Kim, Sangmin Lee
We establish an equivalence between massive spinning particle models in four spacetime dimensions coupled to electromagnetism or gravity, within the spin-magnitude-preserving secto…

Classical eikonal in relativistic scattering
Sungsoo Kim, Hojin Lee, Sangmin Lee
The classical eikonal is defined to be the generator of all scattering observables in a scattering problem in classical mechanics. It was originally introduced as the log of the qu…

Classical eikonal from Magnus expansion
Joon-Hwi Kim, Jung-Wook Kim, Sungsoo Kim +1
In a classical scattering problem, the classical eikonal is defined as the generator of the canonical transformation that maps in-states to out-states. It can be regarded as the cl…
