This particle is created as the result of an electron-positron annhilation resonance at 3.095 GeV.
This particle is created as the result of an electron-positron annhilation resonance at 3.095 GeV. The discovery of this particle is known as the "November Revolution" as it fundamentally shifted the understanding of the structure of matter and gave rise to the Standard Model. A seminal paper by Matsui and Satz found that the suppression of this particle was an unambiguous signature of the formation of a quark-gluon plasma, and this particle is the first excited state of charmonium. For 10 points, name this flavor-neutral subatomic particle composed of a charm quark and a charm antiquark.
