Test of QCD with Heavy Quark Bound States
With the forthcoming results from the electron-positron storage rings PETRA and SPEAR, new possibilities open for the study of new exotic atoms - the bound states of heavy quarks and antiquark pairs. At present, two families of such states have been discovered, but many theoretical studies indicate that at least one more family which consists of bound states of still heavier “top” quark and antiquark pairs may be discovered.

- It is amusing to note here that without strange quarks we find the identical value Λ = 470 MeV (compare with our Pig. 1) as the best fit to the ′onium spectrum.Google Scholar
