[en] A review is made of the relativistic bound state problem formulated on the light cone. The relation between the light cone bound state equation and Bethe-Salpeter equation is discussed, and QCD quark distribution amplitudes are related to the short distance hadron wavefunctions. The generalization to a multiquark system is also demonstrated in a toy dibaryon analysis

[en] Drift chambers are usually used to obtain precise information on particle position resolution and trajectory. The following is a brief description of the construction of a prototype drift chamber for Hall C, which is one of the topics covered by Dr. O.K. Baker in HUGS 1990. The drift chamber contains three types of wires: sense, field, and guard wires

[en] The role of the deuteron D-state observables is examined. Their determination imposes very strong constraints on exotic models of NN- interaction. It is also found that the entire deuteron wave-function is dominated by one pion-exchange

[en] This report contains papers on the following topics: Construction of hall C drift chamber prototype; a construction of the N-N potential; electron scattering; investigating lightcone QCD at CEBAF; lattice gauge theory; low energy NNbar interactions; photo and electroproduction of Baryon resonances in the potential quark model; D-state admixture and tensor force in deuteron; and, notes for a talk at HUGS at CEBAF 1990: Is light cone physics merely a change of coordinates?

[en] Electron scattering is one of the best probes available to us to probe the nucleus. It has revealed to us, with unprecedented accuracy, the charge and current distributions of nuclei. It has provided us with positive evidence for meson exchange currents. It was used to 'discover' the quark and it revealed to us that nucleons may be modified in the nuclear environment (EMC Effect). In short, electron scattering has revolutionized the study of nuclear physics. Several recent developments will insure that electron beams which will soon become availabe at CEBAF, Bates and elsewhere will make high-precision coincidence experiments possible. As the technology is becoming available, we are just beginning to exploit polarization degrees of freedom in our experiments. In this paper, we will introduce the formalism of electron scattering, review what we have learned in the past and look ahead toward the future

[en] The N bar N potential construction from the NN system using the G parity rule is reviewed. Some of the phenomenological treatment of N bar N annihilation data is discussed. This is based on the lectures given by Prof. J.M. Richard at HUGS'90

[en] In an effort to understand the Nucleon-Nucleon interaction in terms of a quantum field theory phenomenon, we treat the exchange of a single boson in analogy with electrodynamics. The authors would like to think of the interaction between nucleons as the result of the exchange of a virtual particle. This approach is not rigorous in nature, although it illuminates some of the most important features of the two nucleon interaction

[en] In this report we attempt to summarize the lattice formulation of Gauge Theories and investigate some of its most important feautures. The lattice provides a natural cut-off in the ultraviolet limit, which eliminates the need for renormalization and, because of its non-perturbative nature, consists is a good framework for the study of confinement in Quantum Chromodynamics. In addition it indicates the possibility of phase transitions and can be used to investigate the strong coupling limit of Gauge Theories. In its path integral formulation, it allows for the direct application of statistical calculations and Mean Field Theory techniques as well as Monte Carlo simulations which lead to exact results. The availability of sophisticated algorithms and fast computers has developed Lattic Gauge Theories into an active research field

[en] The nonrelativistic constituent quark model is a highly successful model for describing a large amount of data. In this paper, the authors introduce a potential quark model and discuss its applications to the electromagnetic transititions of baryon resonances and gluonic hadrons. A SU(6)circle-times O(3) QCD quark model is developed. Bound states and electromagnetic transitions are calculated in a SHO basis, and the results are applied to excited nucleons and gluonic hadrons

[en] The question in the title is an outstanding question which first appeared implicitly in the classic 1949 paper of Dirac on Light cone physics, and later explicitly in the 1978 paper of Leutwyler and Stern. Physical causality requires that if the initial state of a system is specified everywhere on a spacelike surface, then the dynamical laws governing the system must be able to predict the state of the system at any other spacelike surface. This specification of the state of a system on a spacelike surface is necessary in order to ensure physical independence of each point on the surface
