Abstract
The cross sections for Ξ− and Ω− inclusive production in Ξ− Be collisions at 116 GeV/c have been measured in the kinematic domain [0.1<x F <0.9, 0<p T <1.7 GeV/c]. The integrated cross sections per nucleon are found to be about twice as large as in Ξ− p collisions. The invariant cross sections increase by a factor of 70 for the Ξ− s and of 100 for the Ω− s between the central region (x F ∼0.2) and the projectile fragmentation region (x F ∼0.8). In the central region, they have about the same magnitude as the ones for Ξ− and Ω− inclusive production inp nucleon collisions. The Ξ− and Ω− polarisations have been measured over the same kinematic domain and are found to be compatible with zero.
