| dc.description.abstract | 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 gamma(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 presented for the first time. The production cross sections divided by the number of spin states for S = -1 hyperons follow an exponential function with a single slope parameter except for the Sigma(1385)(+) resonance. Suppression for Sigma(1385)(+) and Xi(1530)(0) hyperons is observed. Among the production cross sections of charmed baryons, a factor of 3 difference for Lambda(+)(c) states over Sigma(c) states is observed. This observation suggests a diquark structure for these baryons. | en_US |
