Ξ−, Ω− and antibaryon production in 10 GeV/c K−p interactions

Abstract Production of Ξ − , Ω − and antibaryons has been studied in 10 GeV/ c K − p interactions. The Ξ ∗ (1530) is produced in about 15% of the reactions with Ξ − production. Four unambiguous examples of Ω − production with decay into (ΛK) have been observed: this gives a lower limit for the Ω − production cross section of 2.5 μb. One example of anti-Xi has been found. Distributions and average values of transverse and c.m. longitudinal momenta are presented.
