Search for the exotic Ξ(1860) Resonance in 340GeV/c Σ-Nucleus Interactions / WA89 Collaboration
We report on a high statistics search for the Ξ(1860) resonance in Σ-nucleus collisions at 340GeV/c. No evidence for this resonance is found in our data sample which contains 676000 Ξ candidates above background. [...]

Observation of a resonance in the Ksp decay channel at a mass of 1765 MeV/c2 / WA89 Collaboration
We report on the observation of a Ksp resonance signal at a mass of 1765±5 MeV/c2, with intrinsic width Γ=108±22 MeV/c2, produced inclusively in Σ-nucleus interactions at 340 GeV/c in the hyperon beam experiment WA89 at CERN. The signal was observed in the kinematic region xF>0.7, in this region its production cross section rises approximately linearly with (1xF), reaching BR(XKSp)dσ/dxF=(5.2±2.3)μb per nucleon at xF=0.8.

Determination of the total cc¯ production cross section in 340 GeV/c Σ - nucleus interactions / WA89 Collaboration
The production of charmed particles by Sigma- of 340 Gev/c momentum was studied in the hyperon beam experiment WA89 at the CERN-SPS, using the Omega-spectrometer. In two data-taking periods in 1993 and 1994 an integrated luminosity of 1600 microb^-1 on copper and carbon targets was recorded. [...]

Search for the ϕ(1860) Pentaquark at COMPASS / COMPASS Collaboration
Narrow Xi-pi+- and Xi-bar+pi+- resonances produced by quasi-real photons have been searched for by the COMPASS experiment at CERN. The study was stimulated by the recent observation of an exotic baryonic state decaying into Xi-pi-, at a mass of 1862 MeV, interpreted as a pentaquark. [...]
