Analysis
This paper investigates temperature fluctuations in hot QCD matter using a specific model (PNJL). The key finding is that high-order cumulant ratios show non-monotonic behavior across the chiral phase transition, with distinct structures potentially linked to the deconfinement phase transition. The results are relevant for heavy-ion collision experiments.
Key Takeaways
- •Investigates temperature fluctuations in hot QCD matter.
- •Uses the PNJL model.
- •High-order cumulant ratios show non-monotonic behavior across the chiral phase transition.
- •Structures in cumulant ratios are linked to the deconfinement phase transition.
- •Findings are relevant for heavy-ion collision experiments.
Reference
“The high-order cumulant ratios $R_{n2}$ ($n>2$) exhibit non-monotonic variations across the chiral phase transition... These structures gradually weaken and eventually vanish at high chemical potential as they compete with the sharpening of the chiral phase transition.”
