TheA-dependence of the polarization ofΛ0,s produced inclusively in neutron-nucleus interactions at a mean neutron momentum of about 40 GeV/c has been measured in an experiment performed using the BIS-2 spectrometer at the Serpukhov accelerator. Carbon, Aluminium and Copper targets were used. TheΛ0,s were produced in the kinematical region of 0.6<pT<1.3 GeV/c and 0.2<xF<0.9. Describing the polarization of theΛ0,s by ℘=a·A a value of (−0.15+0.07/−0.60) was obtained by a fit to our data.

New Measurement of the Production Polarization and Magnetic Moment of the Cascade Minus Hyperon

Trost, L.H. ; McCliment, E.R. ; Newsom, C.R. ; et al.
Phys.Rev.D 40 (1989) 1703, 1989.
Inspire Record 280604 DOI 10.17182/hepdata.23053

We have measured the production polarization and magnetic moment of a sample of 89×103Ξ− hyperons produced in the inclusive reaction p(400 GeV/c)+Cu→Ξ−+X. The weighted average of the polarization is -0.070±0.008±0.010 at a pt of 0.63 GeV/c. The Ξ−'s magnetic moment yields the value μΞ=−0.661±0.036±0.036 nuclear magnetons. The first error is statistical, the second systematic.

Single Spin Asymmetry in Inclusive Reactions Polarized $P$, $P$ Goes to $\pi^+$, $\pi^-$, and $P$ at High $P$(t) at 13.3-{GeV}/$c$ and 18.5-{GeV}/$c$

Saroff, S. ; Baller, B.R. ; Blazey, G.C. ; et al.
Phys.Rev.Lett. 64 (1990) 995, 1990.
Inspire Record 26394 DOI 10.17182/hepdata.19960

Data are presented for the left-right asymmetry in inclusive production of π+, π−, and p with proton beams (polarized normal to the scattering plane) of 13.3 and 18.5 GeV/c incident on a LH2 target. At both energies the asymmetry in π+ production grows steadily to about 25% near the kinematic limit, whereas the π− and p asymmetries are consistent with zero over the measured range of pt, 1.1–2.2 GeV/c.

Polarization of Sigma+ and anti-Sigma- hyperons produced by 800-GeV/c protons

The E761 collaboration Morelos Pineda, Antonio ; Albuquerque, I.F. ; Bondar, N.F. ; et al.
Phys.Rev.Lett. 71 (1993) 2172-2175, 1993.
Inspire Record 356301 DOI 10.17182/hepdata.19722

We have mesured the polarization of 375-GeV/c Σ+ and Σ¯ − hyperons produced by 800-GeV/c protons incident on a Cu target. We find that the Σ+ polarization rises with increasing pt to a maximum of 16% at pt=1.0 GeV/c and then decreases to 10% at pt=1.8 GeV/c. We compare this Σ+ polarization with data at lower energies. The Σ¯ − polarization has been measured for the first time. It has the same sign as the Σ+ but smaller magnitude in a similar kinematical region.

$P_{\tau}$ and $X_F$ Dependence of the Polarization of $\Sigma^+$ Hyperons Produced by 800-GeV/c Protons

The E761 collaboration Morelos Pineda, Antonio ; Albuquerque, I.F. ; Bondar, N.F. ; et al.
Phys.Rev.D 52 (1995) 3777-3780, 1995.
Inspire Record 360549 DOI 10.17182/hepdata.42500

We utilize the angle and momentum resolution of our apparatus to study the polarization of 375 GeV/c Σ+ hyperons produced by 800 GeV/c protons incident on a Cu target. By examining in detail two of our high statistics data samples, we find evidence for structure in the pt dependence of Σ+ polarization and are able to extract the xF dependence of the Σ+ polarization and compare it with xF behavior in the Λ0 and Ξ− systems.

Measurement of Lambda(b) polarization in Z decays

The ALEPH collaboration Buskulic, D. ; Casper, D. ; De Bonis, I. ; et al.
Phys.Lett.B 365 (1996) 437-447, 1996.
Inspire Record 402895 DOI 10.17182/hepdata.48060

The Λ b polarization in hadronic Z decays is measured in semileptonic decays from the average energies of the charged lepton and the neutrino. In a data sample of approximately 3 million hadronic Z decays collected by the ALEPH detector at LEP between 1991 and 1994, 462 ± 31 Λ b candidates are selected using ( Λπ + )-lepton correlations. From this event sample, the Λ b polarization is measured to be P Λ b = −0.23 −0.20 +0.24 (stat.) −0.07 +0.08 (syst.).
