Contribution

It provides new insights into the cutoff dependence of chiral and deconfinement transition indicators in lattice QCD with improved staggered actions.

Findings

Chiral and deconfinement transitions are not closely interconnected.

The study discusses cutoff dependence of related quantities.

Contradicts earlier lattice results on the transition relationship.

Abstract

We discuss chiral and deconfinement aspects of the finite temperature transition in QCD using improved staggered actions. We study different quantities related to chiral and deconfinement transition and discuss their cutoff dependence. Contrary to some earlier lattice results we find that the chiral and deconfinement transition are not closely interconnected.
