Inclusive∑± production in\(\bar pp\) interactions at 12 GeV/c

Inclusive production of∑±(1385) resonances is studied in\(\bar pp\) interactions at 12 GeV/c. The cross sections for∑+(1385)+cc and∑− are determined to be 251±38 μb and 123±30 μb, respectively. The inclusive spectra are presented as a function of Feynman x, c.m. rapidity and the squared transverse momentump T 2 . Significant differences with the correspondingpp data are found in the longitudinal momentum distributions. The qualitative features of the production can be explained by simple quark ideas.
