QCD makes the most challenging component of the Standard Theory of
Particle Physics. It is a strong interaction, yet quarks are
asymptotically free. It is unique in harboring the emergent
phenomena of dynamical mass generation and confinement of colored
excitations. It is also astonishingly peculiar in that the
fundamental degrees of freedom which enter the Lagrangian are not
accessible in the detectors. We cannot see quarks and gluons, yet
they conspire to outpour a plethora of hadrons and account for
most mass observed in the visible universe, outshining the Higgs
mechanism almost completely.
Can we aspire to explain the observable world of hadrons, their
static and dynamic properties, starting from the QCD Lagrangian?
The current status is that the detailed understanding of even the
simplest of strongly interacting bound states has been
non-trivially elusive to us.
In this talk, I shall highlight some of the headway we have made
in this direction within the formalism of its fundamental field
theoretic equations of motion.
