Abstract
We develop a new approach to construct the operator on lattice for the
calculation of glueball mass, which is based on the connection between the
continuum limit of the chosen operator and the quantum number \$J^PC\$ of the
state studied. The spin of the state studied is then determined uniquely and
directly in numerical simulation. Furthermore, the approach can be applied to
calculate the mass of glueball states (ground or excited states) with any spin
\$J\$ including \$J4\$. Under the quenched approximation, we present
pre-calculation results for the masses of \$0^++\$ state and \$2^++\$ state,
which are \$1754(85)(86)MeV\$ and \$2417(56)(117)MeV\$, respectively.
