In textbooks it is argued that without QCD, the state of the [[DELTA].
At the same time the strong repulsion of two nucleons at short distances, understood qualitatively in terms of the Fermi statistics of the quarks in the nucleons and the high energy cost of flipping a quark spin in the nucleon, means that the dynamical mechanism for the weak interaction between nucleons must involve meson exchange and the soft QCD physics that leads to it.
He had even invented a computational technique, called lattice QCD, to do just that Bemoaning the dearth of computing power available at the time, however, he concluded that his approach just wasn't worth pursuing.
Nowhere is the gap more striking than for QCD, the theory of strong interactions, which dominates in most high-energy collisions, like at the LHC (Large Hadron Collider) at CERN.

What may be in question, however, is the enterprise of extrapolating from the infinitesimal, quark-scale realm of QCD to the experimentally measurable traits and behaviors of much larger particles, such as protons, neutrons, and mesons.
