Quark and gluon condensates in QCD reevaluated

We compute the quark and gluon condensates in $QCD$ with $N$ colors and $N_f$ flavors based on the renormalization group equations and on the knowledge of a single scale $\Lambda_{QCD}$. For $N=3$ and $N_f=3$ our findings are in the good range for $0.2\leq\Lambda_{QCD}\leq 0.36$ and in excellent agreement with the results in the literature from sum rules for a value $\Lambda_{QCD}=0.28$.
