Abstract

We present a progress report on our investigation of the thermodynamics of QCD with Nf=2N_f=2 flavors of dynamical Wilson fermions in the limit of a large number of colors NcN_c. To date, studies of the thermodynamics of QCD at large NcN_c have been limited to the quenched approximation, i.e., to the behavior of pure SU(Nc)\mathrm{SU}(N_c) gauge theory at large NcN_c. This is the first study of thermodynamics at large NcN_c using dynamical fermions, and thus the first study able to test whether the quenched approximation is a valid way to investigate large NcN_c thermodynamics. After reviewing 't Hooft's large NcN_c limit, we discuss the automation we use to make this study feasible, and finally compare our preliminary physics results for SU(35)\mathrm{SU}(3-5) with large NcN_c expectations.
