These proceedings contain the papers presented during the 14th annual High Energy Physics meeting convened under the aegis of Orbis Scientiae 1977. The title "Deeper Pathways in High Energy Physics" was adopted to indicate either further penetration into the nature of the structure of the elementary particle or the deepening of the continuously trodden path that gets gradually deeper and deeper, evolving into a trench. In the latter instance, the visibility of the real nature of elementary particles may be getting dimmer and dimmer. It is hoped that some of the papers in these proceedings do, indeed, contain further revelations on the "deeper" nature of elementary particles. We must not be overly charmed with "charm" even if it may fit the data of the current generation of e+ and e experiments. It would be much less than prophetic to say that a complete and totally satisfactory theory com~ising the entire physical reality is yet to be discovered, and there is presumably no paper of that kind in these proceedings. Despite this short coming, the editors do not wish to hide their admiration for the caliber of the papers contributed by the participants of Orbis Scientiae 1977. Appreciation is extended to Mrs. Helga S. Billings, Mrs. Elva Brady, and Ms. Yvonne L. Leber for their skillful typing of the proceedings, which they have performed with great enthusiasm and dedication. Orbis Scientiae 1977 received some support from the Energy Research and Development Administration.

The editors are pleased to submit to the readers the state of the art in high energy physics as it appears at the beginning of 1979. Great appreciation is extended to Mrs. Helga S. Billings and Mrs. Connie Wardy for their assistance with the conference and skillful typing of the proceedings which was done with great enthusiasm and dedication. Orbis Scientiae 1979 received some support from the Department of Energy. The Editors v CONTENTS Evidence for Quarks from Neutrino-Nucleon Scattering...... 1 F.

In August 1978 a group of 80 physicists from 51 laboratories of 15 countries met in Erice to attend the 16th Course of the International School of Subnuclear Physics. The countries represented at the School were: Austria, Denmark, Federal Republic of Germany, Finland, France, Israel, Italy, the Netherlands, Sweden, Switzerland, South Africa, Turkey, the United Kingdom, The United States of America, and Yugoslavia. The School was sponsored by the Italian Ministry of Public Education (MPI) , the Italian Ministry of Scientific and Technological Research (MRSI) , the North Atlantic Treaty Organization (NATO), the Sicilian Regional Government, and the Weizmann Institute of Science. As usual, the Course was devoted to a review of the most out standing problems and results in Subnuclear Physics, with particular emphasis on the new aspects; there were mainly two: supersymmetry and electroweak interactions. In his famous lecture at Erice in 1967, Sid Coleman reviewed "All possible symmetries of the S matrix. " All but one, namely that which tells you: if you have a fermion you must have a boson. This is super symmetry , and this produces the superspace, i. e. an entity which has not only the Einstein-"bosonic" coordinates, but also "fermionic" coordinates. From superspace we get supergravity; and this means that one day we should be able to detect not only the graviton (with spin 2) but also the gravitino (spin 3/2). If we add "flavour", "colour", and "family" as other intrinsic degrees of freedom, we get extended supergravity.

The theory of General Relativity, after its invention by Albert Einstein, remained for many years a monument of mathemati cal speculation, striking in its ambition and its formal beauty, but quite separated from the main stream of modern Physics, which had centered, after the early twenties, on quantum mechanics and its applications. In the last ten or fifteen years, however, the situation has changed radically. First, a great deal of significant exper~en tal data became available. Then important contributions were made to the incorporation of general relativity into the framework of quantum theory. Finally, in the last three years, exciting devel opments took place which have placed general relativity, and all the concepts behind it, at the center of our understanding of par ticle physics and quantum field theory. Firstly, this is due to the fact that general relativity is really the "original non-abe lian gauge theory," and that our description of quantum field in teractions makes extensive use of the concept of gauge invariance. Secondly, the ideas of supersymmetry have enabled theoreticians to combine gravity with other elementary particle interactions, and to construct what is perhaps the first approach to a more finite quantum theory of gravitation, which is known as super gravity.
