QCD and strongly coupled gauge theories: challenges and perspectives

N Brambilla, S Eidelman, P Foka, S Gardner… - The European Physical …, 2014 - Springer
We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …
