The Gluon Propagator on a Large Volume, at $\beta =6.0$

Abstract

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 described by the expression $G(k^2)=[M^2+Z\cdot k^2(k^2/{\Lambda }^2{)}^{\eta }{]}^{-1}$. 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 $\beta$.
