Samuel C. C. Ting coauthored the 1974 observation of the narrow particle signal called J. A precise pair spectrometer measured the invariant mass of electron-Positron pairs produced when protons struck beryllium. A sharp feature near 3.1 GeV stood above the smooth background, indicating a new state rather than an arbitrary individual collision. This illustrates how a short-lived particle can be identified through reconstructed decay products.[ref]

Samuel C. C. Ting is a renowned physicist and a Nobel Prize laureate in Physics. He was born on January 27, 1936, in Ann Arbor, Michigan, but he spent part of his early life in China. He is best known for his work in particle physics, particularly for his role in the discovery of the J/ψ particle in 1974, which provided essential evidence for the existence of quarks and helped to establish the field of quantum chromodynamics.
