# Phase structure and propagators at nonvanishing temperature for QCD and QCD-like theories

@article{Contant2017PhaseSA, title={Phase structure and propagators at nonvanishing temperature for QCD and QCD-like theories}, author={Romain Contant and Markus Q. Huber}, journal={Physical Review D}, year={2017}, volume={96}, pages={074002} }

We investigate the universality of truncation schemes for Dyson-Schwinger equations developed for quantum chromodynamics in theories which differ from quantum chromodynamics only in the gauge group. Our specific choices are the gauge groups $SU(2)$ and $G_2$, for which lattice calculations at nonvanishing chemical potential are possible. Thus, corresponding calculations can provide benchmarks for testing calculations with functional equations. We calculate the quark and gluon propagators and…
