Abstract

We calculate the string tension and $0^{+ +}$ and $2^{+ +}$ glueball masses in pure gauge QCD using an improved lattice action. We compare various smearing methods, and find that the best glueball signal is obtained using smeared Wilson loops of a size of about 0.5 fm. Our results for mass ratios $\frac{m_{0^{+ +}}}{\sqrt{σ}} = 3.5 (3)$ and $\frac{m_{2^{+ +}}}{m_{0^{+ +}}} = 1.6 (2)$ are consistent with those computed with the simple plaquette action.
