Abstract
In a recent article, W.-S. Hou and G.-G. Wong [ Phys. Rev. D 67, 034 003 (2003)] have investigated the spectrum of two-gluon glueballs below 3 GeV in a potential model with a dynamical gluon mass. We point out that, among the 18 states calculated by the authors, only three are physical. The other states either are spurious or possess a finite mass only due to an arbitrary restriction of the variational parameter.Keywords
