  1. 1976 Nobel Prize: the J/Psi Particle Awarded for their “pioneering work in the discovery of a heavy elementary particle of a new kind.” Professor Samuel C.C. Ting Professor Burton Richter • J Particle • Collided protons with a beryllium target at rest • Created “daughter particles” (electron and positron) through radiation • Predicted attributes of “parent particle” from “daughter particles” • Difficulties: • Picking a few pairs of • “daughter particles” • from countless other • particles being • produced • Psi Particle • Collided electrons with positrons to create a heavier particle • Particle lived much longer than expected • Difficulties: • Found that the particle • could only be created • at a specific speed of • collision • Used particle accelerators • Years of preparation • Discovered the same particle nearly simultaneously • Implications of discovery: • Essential in understanding the composition of matter • Further supported new dimensions since it takes a fourth quark to understand the J/Psi particle • “Changed the physics of elementary particles” Sources: "Press Release: The 1976 Nobel Prize in Physics".
