Abstract

We present a full result for the 2+1 flavor QCD equation of state. All the systematics are controlled, the quark masses are set to their physical values, and the continuum extrapolation is carried out. This extends our previous studies [JHEP 0601:089 (2006); 1011:077 (2010)] to even finer lattices and now includes ensembles with Nt = 6,8,10,12 up to Nt = 16. We use a Symanzik improved gauge and a stout-link improved staggered fermion action. Our findings confirm our earlier results. In order to facilitate the direct use of our equation of state we make our tabulated results available for download.

  1. What is quantum field theory and why is it incomplete? 1 comment

    • "Solve the theory" is bit of a wish-washy expression. It depends on what you are interested in. What it really means is that it provides an approximation-free prescription for extracting observables from the QCD action. Given some experimentally-measured observables (the pion…
