Description
We measure the inclusive production cross sections of hyperons and
charmed baryons from e+e- annihilation using a 800 fb-1 data sample
taken near the Υ(4S) resonance with the Belle detector at the KEKB
asymmetric-energy e+e- collider. The feed-down contributions from
heavy particles are subtracted using our data, and the direct
production cross sections are compared for the first time. The results
are discussed
from the viewpoint of the diquark structure in baryons.
