英文摘要 | By contrast to the traditional consideration about the structure of the heavy flavor baryons (cqq') where the two light quarks are combined as a (qq') system, we propose two other possible structures of (cqq') where in one case (cq) or (cq') constitutes a color triplet scalar or spin-1 system according to the group analysis and Clebsch-Gordon recombination; in the other case there are diquark structures (cq), (cq') and (qq') in (cqq'). Applying the superflavor symmetry, we calculate the cross sections sigma(e(+)e(-) --> Lambda(c) ($) over bar Lambda(c)), sigma (e(+)e(-) --> Sigma(c) ($) over bar Sigma(c)) and sigma(e(+)e(-) --> D ($) over bar D), as well as their relative ratios which can be measured in experiments with sufficient accuracy. A comparison of the results with that obtained in terms of the three possible structures is given. The distinction is observable and can be tested in sophisticated experiments. |
