Abstract We present an initial study of the thermodynamics of hot lattice QCD using the “density of states” method, which we describe in detail. The raw data were generated from a Monte Carlo simulation of pureSU(3) gauge theory on 83×N t lattices, withN t =2,4,8, at several values of the gauge coupling β. These data, taken at up to eight values of β, are then used to reconstruct the “density of states” as a function of the action and one additional observable. When combined with the proper Boltzmann weight this yieldscurves of quantities of interest as functions of the coupling constant β. These curves then yield the equation of state in a range of temperature, and the corresponding velocity of sound is obtained through appropriate derivatives. We also discuss in detail the errors, limitations, and advantages of the density of states method in its general application to QCD.
