Massive vector bosons in Hamiltonian formulation — •Maria Schlungbaum, Thoralf Chrobok, and Horst-Heino von Borzeszkowski — Institut für Theoretische Physik, Technische Universität Berlin

In the Standard Model of particle physics the vector bosons assume the function of "force carrier particles", i.e. they convey the interaction between massive particles. Their dynamics can be described either by the Proca or Stückelberg Lagrangian density, which both take the form of a singular system. Therefore constraints arise when passing to Hamiltonian formulation. This talk takes a closer look on these constraints and the differences, which may occur due to the gauge invariance of the Stückelberg theory.
