Abstract: We review how nuclear forces emerge from low-energy QCD via chiral effective field theory. The presentation is accessible to the non-specialist. At the same time, we also provide considerable detailed information (mostly in appendices) for the benefit of researchers who wish to start working in this field.

TL;DR: In this article, the importance of light-cone dynamics, the physics of large longitudinal distances, and the presence of point-like quark-gluon configurations in hadrons for the theoretical description of high-energy processes (and especially nuclear shadowing) is explained.

TL;DR: In this paper, it has been realized that there must be corrections to this simple picture, for example, the meson exchange effects which preclude a simple interpretation of the magnetic moment of the deuteron in terms of d-state probability.
Abstract: Classical nuclear theory deals with a many-body system of neutrons and protons interacting nonrelativistically through two-body potentials. It has, of course, long been realized that there must be corrections to this simple picture—for example, the meson exchange effects which preclude a simple interpretation of the magnetic moment of the deuteron in terms of d-state probability. Nevertheless, the availability of beams of pions, and the consequent ability to study the excitation of real isobars in nuclei, has been critical in the realization that for many problems one must develop a theoretical model which explicitly includes pion and isobar degrees of freedom (see, for example, the proceedings of recent topical conferences Cat+ 82, MT 80).

TL;DR: In this paper, it was shown that a wide class of non-Abelian gauge theories have, up to calculable logarithmic corrections, free-field-theory asymptotic behavior.
Abstract: It is shown that a wide class of non-Abelian gauge theories have, up to calculable logarithmic corrections, free-field-theory asymptotic behavior. It is suggested that Bjorken scaling may be obtained from strong-interaction dynamics based on non-Abelian gauge symmetry.

TL;DR: In the quark bag model, the same gluon-exchange forces which make the proton lighter than the $\ensuremath{\Delta}(1236)$ bind six quarks to form a stable, flavor-singlet (with strangeness of - 2) ${J}^{P}={0}^{+}$ dihyperon ($H$) at 2150 MeV as discussed by the authors.

Another isosinglet dihyperon (${H}^{*}$) with ${J}^{P}={1}^{+}$ at 2335 MeV should appear as a bump in $\ensuremath{\Lambda}\ensuremath{\Lambda}$ invariant-mass plots. Production and decay systematics of the $H$ are discussed.

TL;DR: In this paper, a class of non-Abelian gauge theories of strong interactions is described, for which parity sand strangeness are automatically conserved, and for which the nonconservations of parity and strangeness produced by weak interactions are automatically of order alpha /m/sub w/sup 2/ rather than o f order alpha.
Abstract: ABS>A class of non-Abelian gauge theories of strong interactions is described, for which parity sand strangeness are automatically conserved, and for which the nonconservations of parity and strangeness produced by weak interactions are automatically of order alpha /m/sub w/sup 2/ rather than o f order alpha . When such theories are asymptotically free,'' the order- alpha weak corrections to natural zeroth-order symmetries may be calculated ignoring all effects of strong interactions. Speculations are offered on a possible theory of quarks. (auth)

TL;DR: The hyperfine interaction between quarks suggested in chromodynamics can explain the size and pattern of the splittings and the mixing angles observed experimentally in nonstrange, negative parity baryons as discussed by the authors.
