# Towards the glueball spectrum of full QCD

## TL;DR

This paper reports initial lattice QCD results for scalar and tensor glueball masses, as well as torelon energies, using simulations with two light Wilson fermion flavors at specific lattice parameters.

## Contribution

It provides the first results on glueball and torelon masses in full QCD with two light flavors using Wilson fermions at particular lattice settings.

## Key findings

- Glueball masses estimated at different quark masses.
- Torelon energies measured on the lattice.
- Lattice parameters correspond to physical energies of 2.0-2.3 GeV.

## Abstract

We present first results on masses of the scalar and tensor glueballs as well as of the torelon from simulations of QCD with two light flavours of Wilson fermions. The gauge configurations of extent 16^3*32 at beta = 5.6 and kappa = 0.156, 0.157 and 0.1575 have been generated as part of the SESAM collaboration programme. The present lattice resolutions correspond to 1/a = 2.0-2.3 GeV and ratios m(pi)/m(rho) = 0.83, 0.76 and 0.71, respectively. Studies on larger lattice volumes and closer to the chiral limit are in progress.
