Phys. Rev. Lett. 34, 43–45 (1975)Heavy Quarks and e+e- AnnihilationReceived 19 November 1974; published in the issue dated 6 January 1975 The effects of new, heavy quarks are examined in a colored quark-gluon model. The e+e- total cross section scales for energies far above any quark mass. However, it is much greater than the scaling prediction in a domain about the nominal two-heavy-quark threshold, despite σe+e- being a weak-coupling problem above 2 GeV. We expect spikes at the low end of this domain and a broad enhancement at the upper end. © 1975 The American Physical Society URL:
