Following the work in Ref. http://inspirehep.net/record/1670613, we are investigating the Polyakov loop correlator, singlet and octet quark-antiquark correlators, diquark correlators, and screening masses in 2+1 flavor QCD. We are using the highly improved staggered quark (HISQ) action and several lattice spacings at a wide variety of temperatures.
We include more levels of HYP smearing as well as more data for the analysis from which we hope to get better statistics in the long $rT$ range.
The contribution will be a report on the work in progress in the form of a poster.
