- Descrição
- Following the ''(standard)'' Dirac procedure, we describe the spontaneous symmetry breaking in light-front quantized scalar field theory. The zero mode operator of the field is shown to commute with the nonzero mode operators, and thus may be looked upon as a background field. In the light-front framework a nonlocal constraint must be satisfied. The values of the background field at the tree level, as a consequence, are shown to follow from the minimization of the light-front energy functional. We are thus led to a description parallel to the one made in equal-time framework where we appeal to physical considerations and minimize the energy. These values characterize the various (non-perturbative) vacua over which the corresponding physical sectors may be built by applying the non-zero mode operators.
