Hadron Properties just before Deconfinement

TL;DR

This study investigates hadron properties near the QCD deconfinement transition, finding no significant temperature effects on chiral condensate or mesons, but possible effects on nucleon masses, using lattice simulations in the quenched approximation.

Contribution

It provides new insights into hadron behavior near deconfinement by analyzing screening masses and condensates with lattice QCD simulations close to the transition temperature.

Findings

No significant temperature dependence in chiral condensate.

No significant temperature dependence in meson properties.

Possible temperature dependence in nucleon screening mass.

Abstract

We have investigated hadron screening masses, the chiral condensate, and the pion decay constant close to the deconfinement phase transition in the confined phase of QCD. The simulations were done in the quenched approximation, on a lattice of size \mbox{$32^{3}\times 8$}. We examined temperatures ranging from $0.75\tc$ up to $0.92\tc$. We see no sign of a temperature dependence in the chiral condensate or the meson properties, but some temperature dependence for the nucleon screening mass is not excluded.
