Description
I will discuss recent lattice QCD results on equation of state, transition temperature, fluctuations of conserved charges and color screening at vanishing and non-zero baryon density. I will show new results on the equation of state in 2+1 flavor QCD up to temperature 2000 MeV and recent results from Taylor expansion in baryon chemical potential for equation of state and the transition temperature. I will discuss the comparison of the lattice results with weak coupling calculations at high temperatures and hadron resonance gas at low temperature. Finally, I will discuss the length scale of onset of color screening and the effective coupling constant at non-zero temperature.
