The scalar and tensor glueballs in the valence approximation

We evaluate the infinite volume, continuum limit of $0^{++}$ and $2^{++}$ glueball masses in the valence approximation. We find $m_{0^{++}}=1740\pm 71$~MeV and $m_{2^{++}}=2359\pm 128$~MeV, consistent with the interpretation of $f_0(1710)$ as the lightest scalar glueball.
