Abstract
Production behaviours of the open-charm particles described by SUf (4) symmetry have been investigated in this paper. It accounts for observed suppressed productions of the charm baryon Σc, the strange-cum-charm meson Ds, (F in the notation of Gaillard et al.) and its excited state D*s (F*). Also, it has been pointed out that suppression witnessed in Σc-production must be stronger than that in Ds production. Furthermore, this paper predicts which ones of the so far unobserved ½+ charm baryons will be freely produced and which ones of them will undergo suppressed production.
