Equation of State from Lattice QCD Calculations
We provide a status report on the calculation of the Equation of State (EoS)
of QCD at finite temperature using lattice QCD. Most of the discussion will
focus on comparison of recent results obtained by the HotQCD and
Wuppertal-Budapest (W-B) collaborations. We will show that very significant
progress has been made towards obtaining high precision results over the
temperature range of T=150-700 MeV. The various sources of systematic
uncertainties will be discussed and the differences between the two
calculations highlighted. Our final conclusion is that the lattice results of
EoS are getting precise enough to justify being used in the phenomenological
analysis of heavy ion experiments at RHIC and LHC.Comment: Plenary talk at the ICPAQGP2010, Goa, India, Dec 201
