## Abstract

The deconfining chiral transition in finite-temperature QCD is studied on the lattice using Wilson quarks. After discussing the nature of chiral limit with Wilson quarks, we first study the case of two degenerate quarks $N\_F=2$, and find that the transition is smooth in the chiral limit on both $N\_t=4$ and 6 lattices. For $N\_F=3$, on the other hand, clear two state signals are observed for $m\_q \\simm{\<} 140$ MeV on $\\nt=4$ lattices. For a more realistic case of $N\_F=2+1$, i.e.\\ two degenerate u and d-quarks and a heavier s-quark, we study the cases $m\_s \\simeq 150$ and 400 MeV with $m\_u = m\_d \\simeq 0$: In contrast to a previous result with staggered quarks, clear two state signals are observed for both cases, suggesting a first order QCD phase transition in the real world.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
