Abstract: | A Monte Carlo calculation of the gluon propagator in the Landau gauge in SU(3) lattice gauge theory is described. The results of calculations at β = 5.6 (200 43 × 8 lattices), β = 5.8 (400 43 × 10 lattices and 100 63 × 12 lattices), and β = 6.0 (100 43 × 8 lattices) indicate that the gluon propagator resembles a massive particle propagator in which the mass grows with separation. At the largest distances accessible with these lattices, the mass is about 600 MeV. |
