Glueball mass measurements from improved staggered fermion simulations
We present the first 2+1 flavor spectrum measurements of glueball states using high statistics simulations with improved staggered fermions. We find a spectrum consistent with quenched measurements of scalar, pseudoscalar, and tensor glueball states. The measurements were made using 5000 configurati...

| description | We present the first 2+1 flavor spectrum measurements of glueball states using high statistics simulations with improved staggered fermions. We find a spectrum consistent with quenched measurements of scalar, pseudoscalar, and tensor glueball states. The measurements were made using 5000 configurations at a lattice spacing of 0.123 fm and pion mass of 280 MeV and 3000 configurations at 0.092 fm with a pion mass of 360 MeV. We see some evidence of coupling to 2{pi} states. We compare our results with the experimental glueball candidate spectrum as well as quenched glueball estimates. |
