Abstract

We extend our work on QCD thermodynamics with 2+1 quark flavors at nonzero chemical potential to finer lattices with Nt=6. We study the equation of state and other thermodynamic quantities, such as quark number densities and susceptibilities, and compare them with our previous results at Nt=4. We also calculate the effects of the addition of the charm and bottom quarks on the equation of state at zero and nonzero chemical potential. These effects are important for cosmological studies of the early Universe.
