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, the authors describe low-energy kaon-nucleon scattering by generalizing the cloudy bag model (CBM) to SU(3) chiral symmetry.

TL;DR: In this article, the experimental data for the slope of the rapidity distribution of the Drell-Yan process p on Pt favour the existence of an increase in the sea for a bound nucleon.

TL;DR: In this article, a way to measure the six-quark component in the deuteron from a comparison of the structure functions in ep and ed deep-inelastic scattering and the structure function in..nu..p and nu-barp scattering is discussed.
Abstract: We discuss a way to measure the ''six-quark'' component in the deuteron from a comparison of the structure functions in ep and ed deep-inelastic scattering and the structure functions in ..nu..p and nu-barp scattering. Such a determination is obtained by looking at the deviation from 1 in the ratio T = d(x)u(x)/u(x)d(x), where u and d are the quark distributions determined from ..nu..p and nu-barp, and u and d are the effective quark distributions determined from ep and ed by neglect of coherent six-quark effects.

TL;DR: In this paper, a hybrid quark-nucleon model of nuclei is developed in which nucleons merge into multiquark bags at short distances, and the model is applied to calculate mass differences between mirror nuclei.
Abstract: A hybrid quark-nucleon model of nuclei is developed in which nucleons merge into multiquark bags at short distances. This model is applied to calculate mass differences between /sup 3/He and /sup 3/H and a number of other mirror nuclei. For light nuclei we obtain a reduction of the discrepancy between experiment and conventional theory. Probabilities for the formation of six-quark bags and nine-quark bags in these nuclei are evaluated, and the consequences of our results are discussed. In particular we comment on the compatibility of conventional and the hybrid quark-nucleon results.

TL;DR: In this paper, a brief review of the connection between QCD and the more phenomenological, chiral bag models, which have generated so much excitement recently, is given, together with a discussion of the evidence from deep-inelastic scattering which supports this choice.
