THE GLUON PROPAGATOR ON A LARGE-VOLUME, AT BETA=6.0

We present the results of a high statistics lattice study of the gluon propagator, in the Landau gauge, at beta = 6.0. As suggested by previous studies, we find that, in momentum space, the propagator is well dcscribed by the expression G(k(2)) = [M(2) + Z . k(2)(k(2)/Lambda(2))(eta)](-1). By comparing G(k(2)) on different volumes, we obtain a precise determination of the exponent eta = 0.532(12), and verify that M(2) does not vanish in the infinite volume limit. The behaviour of eta and M(2) in the continuum limit is not known, and can only be studied by increasing the value of beta.
