Lattice QCD at finite temperature : present status
P. Petreczky
TL;DR
This paper reviews recent advances in finite temperature lattice QCD, focusing on Equation of State, charge fluctuations, correlation functions, and comparisons with various theoretical models and AdS/CFT predictions.
Contribution
It provides a comprehensive overview of current lattice QCD results at finite temperature and compares them with multiple theoretical approaches.
Findings
Lattice results for Equation of State and fluctuations align with hadron resonance gas model at low temperatures.
Spatial correlation functions show consistency with effective field theory predictions.
Ratios of lattice results agree with AdS/CFT correspondence in certain regimes.
Abstract
I review recent progress in finite temperature lattice calculations, including calculations of Equation of State, fluctuations of conserved charges and spatial correlation functions. I compare lattice results with the predictions of hadron resonance gas model, resummed perturbation theory and 3-dimensional effective field theory. Comparison of the lattice results for certain ratios with the prediction of AdS/CFT correspondence is also discussed.
