Generalized Lagrangians and Spinning Particles

  • Published:
Ukrainian Mathematical Journal Aims and scope

Abstract

We show that the spin structure of elementary particles can be naturally described by the generalized Ostrogradskii Lagrangians depending on higher-order derivatives. One component of a spin is related to the rotation of a particle and the other one, caused by the dependence of a Lagrangian on the acceleration, is known as a zitterbewegung component of spin.
