摘要:

A review of present knowledge about the scaling of the neutron and proton structure functions and about the neutron to proton cross section ratio is presented. Emphasis is placed on the results of a recent electron scattering experiment at SLAC from which neutron cross sections were extracted from deuterium data using an impulse approximation.

摘要:

We discuss in simple physical terms two recently proposed field theoretic mechanisms which may shed light on deep inelastic phenomena. Certain gauge theories of quarks can have the short distance and light cone properties of quark fields without their production in scattering experiments. Gauge theories can also be free at short distances and lead to asymptotic Bjorken scaling broken only by logarithms. These proposals suggest non‐abelian gauge theories of colored quarks as the field‐theoretic basis of strong interactions.

摘要:

In this talk, I want to give an overview of structure and development within the unified gauge theory of strong, weak, and electromagnetic interactions. This type of model gives anexplicitrenormalizable description of all known particles with spinJ ≤ 1, plus a few conjectured ones like W‐mesons etc. By “all”, I meanall, including such diverse particles as &rgr;‐mesons, quarks, pion, kaons, Buddha (1235) meson, &rgr;′ (1600), leptons, etc. In these models, all spectra and forces between particles derive from spontaneously broken gauge invariance and incorporate the ideas of Yang and Mills,1Weinberg,2Salam,3‘tHooft,4and others.I will begin by briefly reviewing the structure of these models, go on to describe some of the more striking results therein, and finally end by comparing these models with the “underlying‐field” or quark models advocated by other workers. Although there are some important differences, it appears that, in general, our models here (M‐models) are closely connected to the quark models‐‐the former providing a lower energy explicit realization of the latter. The M‐models also provide us with a surprising number of high‐energy bonuses.
