50 Years of QCD : a Physical Review Collection

2023 marks the 50th Anniversary since the phenomenon of asymptotic freedom was discovered in QCD.  What this meant was that the QCD theory describes nearly free-moving quarks with protons and neutrons as was seen in scattering experiments. 

It is remarkable that a single theory explains both weakly-interacting quark-gluons within hadrons, as well as leads to the emergence of the entire spectrum of hadrons.  

To celebrate the 50th Anniversary of QCD, the editors of Physical Review have put together a Collection of papers relating to important advancements in understanding the theory and its consequences.
