This volume contains the proceedings of the above meeting which attracted over 100 physicists from the United States, Canada, and Europe. MRST-94 explored a wide variety of current issues ranging from the formal aspects of theoretical high-energy physics (conformal field theory, strings, supersymmetry, black holes, new field-theoretic techniques, non-perturbative methods, and finite-temperature field theory) to the more phenomenological (mass generation, heavy quarks, CP violation, weak decays, neutrino physics, cosmic phenomena, heavy-ion physics, collider physics, and issues surrounding the recent evidence for the top quark). This volume thus provides a broad overview of recent developments in theoretical high-energy physics.
