# Quark and gluon condensates in QCD reevaluated

## TL;DR

This paper reevaluates quark and gluon condensates in QCD using renormalization group equations and a single scale, providing results consistent with existing sum rule estimates for specific parameters.

## Contribution

It offers a new calculation method for QCD condensates based on renormalization group equations and a single scale parameter.

## Key findings

- Results align with sum rule estimates for  .28 GeV
- Condensate values are consistent within 0.2 to 0.36 GeV .36 GeV range
- Provides a reevaluation framework for QCD condensates

## Abstract

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 $\Lambda_{QCD}=0.28$.
