Phys. Rev. D 30, 2310–2315 (1984)Indications of hard diquarks in e+e- annihilationReceived 27 December 1983; revised 30 January 1984; published in the issue dated 1 December 1984 It is suggested that very small spin-0 diquarks are directly produced in e+e- annihilation and then fragment into leading baryons and other hadrons. The most influential diquark is the charmed diquark (uc), due to its high charge. It gives a sizable contribution to the hadronic R factor and to the two-jet angular distribution in the energy region W=4-8 GeV. At these energies, a careful study of Λ production would provide the best additional test of the model. © 1984 The American Physical Society URL:
