Polarization in Inclusive $\Lambda$ and $\bar{\Lambda}$ Production at Large $p_T$

Lundberg, B. ; Handler, R. ; Pondrom, L. ; et al.
Phys.Rev.D 40 (1989) 3557-3567, 1989.

A study of the inclusive polarization of Λ hyperons produced by 400-GeV/c protons incident on nuclear targets has been performed at Fermilab. The polarization P of the Λ has been mapped over a large range of xF and pT to good precision for pT up to 3.8 GeV/c. The magnitude of the polarization at fixed xF rises with pT to a plateau at about 1 GeV/c, and the size of the plateau increases monotonically with xF. The Λ¯ were found to be unpolarized for pT<2.4 GeV/c. A target-nucleus dependence for the Λ polarization has been observed.

Production of Xi0 and anti-Xi0 hyperons by 400-GeV Protons

Beretvas, A. ; Deck, L. ; Devlin, T. ; et al.
Phys.Rev.D 34 (1986) 53-74, 1986.
Inspire Record 233799 DOI 10.17182/hepdata.23426

Inclusive production cross sections have been measured for the processes p+A→Ξ0+X (A=Be, Cu, Pb) and for p+Be→Ξ¯0+X. Data were taken at angles of 0, 2, 3.5, 7.3, and 9.8 mrad between the incident 400-GeV proton beam and the outgoing hyperon beam. Production cross sections for Λ and Λ¯ production were measured at the same time. The A dependence of the Ξ0 cross sections is discussed, along with interpretations in terms of various models.
