Two loop effective potential for < A^2_μ> in the Landau gauge in quantum chromodynamics
R. E. Browne, J. A. Gracey
We construct the effective potential for the dimension two composite operator 1/2 A^{a 2}_μin QCD with massless quarks in the Landau gauge for an arbitrary colour group at two loop…

A determination of <A^2> and the non-perturbative vacuum energy of Yang-Mills theory in the Landau gauge
D. Dudal, H. Verschelde, R. E. Browne +1
We discuss the 2-point-particle-irreducible (2PPI) expansion, which sums bubble graphs to all orders, in the context of SU(N) Yang-Mills theory in the Landau gauge. Using the metho…
