Abstract

We calculate glueball and torelon masses as well as the lowest lying hybrid potential in addition to the static ground state potential in lattice simulations of QCD with two flavors of dynamical Wilson fermions. The results are obtained on lattices with 16/sup 3/*32 and 24/sup 3/*40 sites at beta =5.6, corresponding to a lattice spacing a/sup -1/=2.65/sub -8//sup +5/ GeV, as determined from the Sommer force radius, at physical sea quark mass. The range spanned in the present study of five different quark masses is reflected in the ratios 0.83 gt or=m/sub pi //m/sub rho / gt or=0.57
