A Gauge-fixed Hamiltonian for Lattice QCD
J. B. Bronzan, Timothy E. Vaughan
TL;DR
This paper introduces a gauge fixing method for lattice QCD in 2+1 dimensions within the Hamiltonian framework, extending previous pure gauge work to include matter fields and generalize to other theories.
Contribution
It presents a Hamiltonian reformulation of lattice QCD with gauge fixing that incorporates matter fields, broadening the applicability of previous pure gauge approaches.
Findings
Hamiltonian expressed in gauge-invariant variables except for a global transformation
Method generalizes to other theories and dimensions
Includes matter fields in the gauge fixing approach
Abstract
We study the gauge fixing of lattice QCD in 2+1 dimensions, in the Hamiltonian formulation. The technique easily generalizes to other theories and dimensions. The Hamiltonian is rewritten in terms of variables which are gauge invariant except under a single global transformation. This paper extends previous work, involving only pure gauge theories, to include matter fields.
