Aubert and colleagues: experimental observation of the heavy particle J

What changed

Reported a sharp heavy-particle J signal around 3.1 GeV in Brookhaven collision data.

Scientific scope

The record is the exact fourteen-author 1974 Brookhaven experiment. The concurrent SLAC discovery, later charm interpretation and broader November Revolution remain distinct contributions.
