Glueball wave functions in lattice gauge calculations

The SU(2) glueball wave functions 〈0\ensuremath{\Vert}${\mathit{A}}_{\mathrm{\ensuremath{\mu}}}^{\mathrm{\ifmmode^\circ\else\textdegree\fi{}}}$(x)${\mathit{A}}_{\ensuremath{\nu}}$(y)\ensuremath{\Vert}G〉 are measured on the lattice in the Coulomb gauge, using a source method. It is found that the tensor glueball is about 4 times as large as the scalar glueball. Phenomenological implications for identifying glueballs are discussed.
