QCD20 is the 23th International Conference in Quantum Chromodynamics held in Montpellier since 1985. 

The conference discusses all aspects of (non-)perturbative QCD, hadron physics, physics at LHC and of the Standard Model and Beyond. 

It involves regularly about 60-80 participants with an (almost) equal number of experimental annd theoretical physicists in the field. 

It also gives to the young PhD students and Post-Docs the opportunity to present (often for the first time) their works at the international level in front of mondial experts in the field.
