In this proposal we describe an experimental program to carry out high sensitivity searches for a variety of possible new particles, and high sensitivity measurements of known but rarely produced states.
In this overview we give a brief description of the goals and techniques of the experiment. This should provide an overall understanding of the experiment, and set the stage for a careful reading of the sections following. The individual sections on the physics, experimental method, etc., provide the detail needed to understand our goals and our claims regarding sensitivities and background rejections.
We point out that our design for E864, and our understanding of the physics potential of the high energy heavy ion collisions, was strongly influenced and encouraged by the participation of some of us in AGS experiment E814.
