Lattice QCD at finite temperature: present status Original Research Article

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.
