Book Description
The problem of nucleon-antinucleon (N anti N) annihilation is discussed in terms of the underlying quark-gluon dynamics of QCD. It is shown how recently observed selection rules exert a strong constraint on the effective quark-antiquark (Q anti Q) creation/destruction operator which enters in the annihilation process. The data on two meson modes suggest that a Q anti Q operator with one gluon quantum numbers is inadequate, and that a strong coupling approach to the treatment of the gluonic degrees of freedom is more appropriate. 25 refs., 1 fig.

Book Description
Recent progress towards a microscopic understanding of nucleon- antinucleon N/ovr N/ annihilation is reviewed. We consider statistical models, the constraints imposed by SU(2) or SU(3) flavor symmetry and the spin-flavor-color dependence of effective operators for the creation/destruction of quark-antiquark (Q/ovr Q/) pairs in N/ovr N/ annihilation processes. The importance of dynamical selection rules is emphasized as a means of revealing the underlying reaction mechanism. 15 refs., 1 fig.

Book Description
This volume contains the Proceedings of the "XXIV. Inter nationale Universitatswochen fur Kernphysik" held in Schlad ming, Austria, in February 1985. It consists of the written versions of the lectures (3-4 hours) given at this winter school and includes also most of the seminars (30-50 minutes) presented. In choosing the topic for the 1985 meeting, our aim was to give an account of the present understanding of the nucleon-nucleon as well as nucleon-antinucleon inter actions. This field, which is of definite relevance in nuclear and particle physics, has witnessed a rapid develop ment in recent times both in theory and experiment. New evidence has emerged in the whole range from low to extremely high energies. It was an exciting experience to bring to gether knowledge from the very domains of nuclear and high energy physics as well as to meet the respective researchers. Thanks to the efforts of the lecturers, who did a splendid job in presenting the lectures and in preparing their lecture notes, a comprehensive insight into the hadronic interaction between nucleons and anti-nucleons was achieved. The lecture notes were reconsidered by the authors after the meeting and are now being published in their final form. The seminars mainly dealt with specific topics currently under investiga tion within this rather wide field. We are grateful to all authors for their efforts, as they made it possible to speed up the publication of these proceedings.
