Spherical gauge fields

We introduce the spherical field formalism for free gauge fields. We discus s the structure of the spherical Hamiltonian for both general covariant gau ge and radial gauge and point out several new features not present in the s calar field case. We then use the evolution equations to compute gauge-fiel d and field-strength correlators. (C) 1999 Published by Elsevier Science B. V. All rights reserved.
