Glueball spectrum from $N_f=2$ lattice QCD study on anisotropic lattices

Understand

The lowest-lying glueballs are investigated in lattice QCD using $N_f=2$ clover Wilson fermion on anisotropic lattices.

• We simulate at two different and relatively heavy quark masses, corresponding to physical pion mass of $m_\pi\sim 938$ MeV and $650$ MeV.
• The quark mass dependence of the glueball masses have not been investigated in the present study.
• Only the gluonic operators built from Wilson loops are utilized in calculating the corresponding correlation functions.
