A Tale Of A Particle With Two Names

Physics Focus this week has a brief but fascinating history of the J/Psi particle and its discovery that led to it having two different names.

When two separate groups, using different types of accelerators, get practically the same result, it is difficult not to be convinced by something like that. Ah, but back then, way back in the 70's, the US had several high energy physics colliders like this where multiple facilities were producing results.

Now, the US has none, not even one (RHIC and CEBAF are nuclear physics facilities/colliders).
