Lightfront Hamiltonian Structures for the Nonlinear Sigma Model

High Energy Physics - Theory 2009-10-31 v2

Abstract

We derive the Dirac brackets for the O(N) nonlinear sigma model in the lightfront description with and without the constraint. We bring out various subtleties that arise including the fact that anti-periodic boundary condition seems to be preferred.
