The gluon is massive: A lattice calculation of the gluon propagator in the Landau gauge

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 4 3 ×8 lattices), β =5.8(400 4 3 ×10 lattices), and β =6.0(100 4 3 ×8 lattices) indicate that the gluon propagator resembles a massive particle propagator with asymptotic mass near 600 MeV.

The first is obtained from high temperature expansions of the free energy of a massive gluon, while the second is derived by demanding color neutrality over a certain length scale.
