Scenario for Ultrarelativistic Nuclear Collisions: III. Gluons in the expanding geometry
Abstract
We derive expressions for various correlators of the gauge field and find the propagators in Hamiltonian dynamics which employs a new gauge Aτ=0. This gauge is a part of the wedge form of relativistic dynamics suggested earlier as a tool for the study of quantum dynamics in ultra-relativistic heavy ion collisions. We prove that the gauge is completely fixed. The gauge field is quantized and the field of radiation and the longitudinal fields are unambiguously separated. The new gauge puts the quark and gluon fields of the colliding hadrons in one Hilbert space and thus allows one to avoid factorization.
