Abstract: In June 1964, James Bjorken and Sheldon Glashow proposed a brand-new quantum number“charm”in their paper entitled“Elementary particles and ^SU(4)”. This new quantum number implied a new elementary particle, the hypothetical charm quark that had not been observed in various high-energy physics experiments until November 1974, when the charmonium J/ψ—formed by charm quark and its antiparticle—was independently discovered by Sam Ting and Burton Richter. This great discovery, known as the“November Revolution”, is an important milestone in the history of particle physics. It not only meant that the glorious “2G”era of quark physics started, but also had a high impact on the development of experimental and theoretical particle physics in China.
