AMADOR, A. Relativistic particles with auxiliary variables. Rev. mex. fis. [online]. 2007, vol.53, suppl.4, pp.1-4. ISSN 0035-001X.

We consider the motion of a particle described by an action that is a functional of the one-dimensional metric of the worldline and its first Frenet-Serret [FS] curvature. The metric and the curvature along with the orthogonal [FS] basis which connect them to the embedding functions defining the worldline are introduced as auxiliary variables by adding appropiate constraints. The conserved stress tensor associated with the theory is established in terms of the constraints.

Keywords : Relativistic particle.
