Title: A Numerical Approach to Coulomb Gauge QCD

Abstract:
We calculate the ghost two-point function in Coulomb gauge QCD with a 
simple model vacuum gluon wavefunction using Monte-Carlo integration. 
This approach extends the previous analytic studies of the ghost 
propagator in this ansatz, where a ladder-rainbow expansion was unavoidable 
for calculating the path integral over gluon field configurations. This 
approach allows us to study the Coulomb potential derived from the ghost 
dressing function and give insight into phenomenological models within 
Coulomb gauge formalism used in calculations of hadronic properties.
