A measurement of $\Lambda$ polarization in inclusive production by $\Sigma^-$ of 340-GeV/c in C and Cu targets / Adamovich, M I (LPI, Moscow (main)) ; Alexandrov, Yu A (LPI, Moscow (main)) ; Baranov, S P (LPI, Moscow (main)) ; Barberis, D (Genoa U. ; INFN, Genoa) ; Beck, M (Heidelberg, Max Planck Inst.) ; ́erat, C B (Grenoble, CEN) ; Beusch, W (CERN) ; Boss, M (Heidelberg U.) ; Brons, S (Heidelberg, Max Planck Inst.) ; Brückner, W (Heidelberg, Max Planck Inst.) et al. /WA89
We have measured the polarization of $\Lambda$ hyperons produced inclusively by a $\Sigma^-$ beam of 340 GeV/c momentum in nuclear targets. From a sample of 9.5 millions of identified $\Lambda$ decays, polarizations were determined in the range $x_F \gt 0.1$ and $p_t\leq 1.6$ GeV/c . [...]

Observation of a resonance in the K$_s$p decay channel at a mass of 1765 MeV/c$^2$ / WA89 Collaboration
We report on the observation of a K$_s$p resonance signal at a mass of 1765$\pm$5 MeV/c$^2$, with intrinsic width $\Gamma = 108\pm 22$ MeV/c$^2$, produced inclusively in $\Sigma^-$-nucleus interactions at 340 GeV/c in the hyperon beam experiment WA89 at CERN. The signal was observed in the kinematic region $x_F>0.7$, in this region its production cross section rises approximately linearly with $(1-x_F)$, reaching $BR(X\to K_S p)\cdot d\sigma /dx_F = (5.2\pm 2.3) \mu b $ per nucleon at $x_F=0.8$.

A measurement of $\Xi^{-}$ polarization in inclusive production by $\Sigma^{-}$ of 340 GeV/c in C and Cu targets / WA89 Collaboration
We have measured the polarization of Xi /sup -/ hyperons produced inclusively by a Sigma /sup -/ beam of 340 GeV/c momentum in nuclear targets. From a sample of 880000 identified Xi /sup -/ decays, polarizations were determined in the range 0<x/sub F/<0.9 and p/sub t /<or=1.6 GeV/c. [...]

Search for the pentaquark candidate $\Theta^+$(1540) in the hyperon beam experiment WA89 / WA89 Collaboration
We report on a high-statistics search for the \t1540 resonance in $\Sigma^-$-nucleus collisions at 340 \gevc1 . No evidence for this resonance was found in our data sample which contains 13 millions $K^0_s \to \pi^+\pi^- $ decays above background. [...]

D sup * sup+- production in 350 GeV/c pi sup - -N interactions / Adinolfi, M ; Alexandrov, Yu A ; Angelini, C ; Barberis, D ; Cardini, A ; Ceradini, F ; Dameri, M ; Darbo, G ; Duane, A ; Flaminio, V et al.
We report measurements of D sup * sup+- production in interactions between 350 GeV/c pi sup - particles and nuclei. Reconstruction of the decay D sup * sup + -> D sup 0 pi sup + and charge conjugate, with D sup 0 identified via its decays to K sup -pi sup + and K sup -pi sup -pi sup +pi sup + , has allowed isolation of a sample of 611 +- 28 D sup * sup+- mesons, produced at positive x sub F.

Inclusive J/psi and psi' production in pi sup - -nucleus interactions at sq root s approx = 26 GeV / Alexandrov, Yu A ; Angelini, C ; Barberis, D ; Ceradini, F ; Dameri, M ; Darbo, G ; Duane, A ; Flaminio, V ; Forino, A ; French, Bernard R (CERN) et al.
Charmonium production by 350 GeV/c negative pions incident on tungsten, copper and silicon has been studied in the WA92 experiment. J/psi and psi' mesons are identified through their decays into muon pairs and are selected in the Feynman-chi range chi sub F > 0. [...]
