We consider pure glue QCD at β = 5.7, β = 6.0 and β = 6.3. We evaluate the gluon propagator both in time at zero 3-momentum and in momentum space. From the former quantity we obtain evidence for a dynamically generated effective mass, which at β = 6.0 and β = 6.3 increases with the time separation of the sources, in agreement with earlier results. The momentum space propagator G(k) provides further evidence for mass generation. In particular, at β = 6.0, for k ≤ 1 GeV, the propagator G(k) can… CONTINUE READING
