Indications of hard diquarks in e+e- annihilation
1984 (English)In: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 30, no 11, p. 2310-2315Article in journal (Refereed) Published
Abstract [en]

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.
