Description
We investigate medium effects on mesonic screening lengths for QCD with
2-flavours of dynamical staggered quarks on lattices with cutoff a=1/6T.
In our study, T ranges from 0.89 Tc to 1.92 Tc, spanning both the hadronic
and the quark-gluon plasma phases. While chiral symmetry restoration in the
vector channel appears to take place near Tc, it is seen in the scalar channel
only above 1.33 Tc. Varying spatial lattice sizes, we find very little volume
dependence in our results at 0.94 Tc, which is the expected critical end point
temperature. This suggests that the scalar does not decay. We also comment
on the nature of interactions around Tc and beyond.
