Conformal symmetry for relativistic point particles: an addendum
arXiv:1412.6903 · doi:10.1103/PhysRevD.91.047901
Abstract
We extend the results of our previous work on the conformal invariant description of two relativistic point particles. We consider here the most general lagrangian by using a conformal tensor , transforming as a Wilson line, and that allows us to construct invariant expressions for velocities taken at two different space-time points.
