A new determination of the $\Lambda^{0}$ mean life / Althoff, K H ; Brown, R M ; Freytag, D ; Heard, K S ; Heintze, J ; Mundhenke, R ; Rieseberg, H ; Soergel, Volker ; Stelzer, H ; Wagner, A
From 6582 kinematically-reconstructed Lambda /sup 0/ to p pi decays observed in an optical spark chamber, the Lambda /sup 0/ lifetime was evaluated to be tau /sub Lambda /=(2.69+or-0.05)*10/sup -10/ sec. This value is a factor of 1.067+or-0.020 higher than the present world average. [...]

Search for $\Delta S=2$ decays of neutral $\Xi$-hyperons / Geweniger, C ; Eisele, F ; Gjesdal, S ; Kleinknecht, K ; Lüth, V ; Presser, G ; Steffen, P ; Steinberger, J ; Vanucci, F ; Wahl, H et al.
A search for the decay Xi /sup 0/ to p pi /sup -/ has been performed in a neutral hyperon beam derived from the 24 GeV/c external proton beam at CERN. The experiment gives as a 90% confidence upper limit for the branching ratio Gamma ( Xi /sup 0/ to p pi /sup -/)/ Gamma ( Xi /sup 0/ to Lambda pi /sup 0/) <3.6*10/sup -5/. [...]

A high-statistics determination of the $\Lambda^{0}$ mean lifetime / Clayton, E F (Imperial Coll., London) ; Bacon, Trevor C (Imperial Coll., London) ; Butterworth, Ian (Imperial Coll., London) ; Conforto, Bianca (Rutherford) ; Gopal, G P (Rutherford) ; Kalmus, George Ernest (CERN ; Rutherford) ; Ross, R T (Rutherford) ; Van Horn, A J (Rutherford) ; Waters, R M (Imperial Coll., London)
Recent determinations of the mean lifetime of the Lambda hyperon have given values significantly greater than the previously accepted world average. Using 34000 Lambda to p pi /sup -/ decays in the CERN 2m. [...]

A measurement of the $\beta$-parameter in the charged nonleptonic decay of the $\Lambda^{0}$ hyperon / Cleland, W E ; Conforto, G ; Eaton, G H ; Gautschi, A ; Gerber, H J ; Heer, E ; Reinharz, Max ; Revillard, C ; von Dardel, Guy F
The authors obtain for the beta -parameter in the decay Lambda /sup 0/ to pi /sup -/p the value beta =-0.094+or-0.060. This value agrees with the theoretical prediction based on T-invariance and the mod Delta I mod =/sup 1///sub 2/ rule, taking into account the effects of final state interactions. [...]

Hyperon decays and QCD / Gaillard, J M ; Basdevant, J L ; Gastmans, Raymond ; Jacob, Maurice René Michel ; Speiser, D ; Weyers, J
In an experiment in the CERN Super Proton Synchrotron (SPS) charged hyperon beam, 2400 Omega /sup -/ decays have been collected. The analysis of the Omega /sup -/ sample has given an accurate measurement of the Omega /sup -/ lifetime ( tau ( Omega /sup -/)=(0.822+or-0.028) *10/sup -10/ s) and the first determination of the Omega /sup -/ decay branching ratios.

A measurement of the lifetimes of Xi /sup 0/ and Lambda hyperons / Zech, G ; Dydak, F ; Geweniger, C ; Kleinknecht, K ; Navarria, Francesco Luigi ; Overseth, O E ; Steffen, P ; Taureg, H ; Wahl, H ; Williams, E G H
The mean lifetimes of the Lambda and Xi /sup 0/ hyperons have been measured in a short neutral beam at the CERN Proton Synchrotron. Lambda and Xi /sup 0/ decays have been identified by measuring their decay products in a magnetic spectrometer and in a lead glass hodoscope. [...]
