Query: QCD and strongly coupled gauge theories: challenges and perspectives   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 broad sweep of physical problems, in settings ranging
from astrophysics and cosmology to strongly-coupled, complex systems in
particle and condensed-matter physics, as well as to searches for physics
beyond the Standard Model. We also discuss how success in describing the strong
interaction impacts other fields, and, in turn, how such subjects can impact
studies of the strong interaction. In the course of the work we offer a
perspective on the many research streams which flow into and out of QCD, as
well as a vision for future developments.
