Variational Approach to Yang--Mills Theory with non-Gaussian Wave Functionals
arXiv:1011.4798 · doi:10.1063/1.3574979
Abstract
A general method for treating non-Gaussian wave functionals in quantum field theory is presented and applied to the Hamiltonian approach to Yang-Mills theory in Coulomb gauge in order to include a three-gluon kernel in the exponential of the vacuum wave functional. The three-gluon vertex is calculated using the propagators found in the variational approach with a Gaussian trial wave functional as input.
