A-dependence of Polarization of $\Lambda^0$ Produced Inclusively in Neutron - Nucleus Interactions

The BIS-2 collaboration Aleev, A.N. ; Arefev, V.A. ; Balandin, V.P. ; et al.

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.

Inclusive measurements of the p p --> p n pi+ reaction at 420-MeV and 500-MeV.

Pleydon, R.G. ; Falk, W.R. ; Benjamintz, M. ; et al.

Inclusive measurements of the pion differential cross sections and analyzing powers have been carried out for the pp→pnπ+ reaction at 420 and 500 MeV using the SASP spectrometer at TRIUMF. Pion energies from the onset of the continuum down to about 25 MeV were covered in the angular range from 23° to 100° (lab). Total cross sections of 0.750±0.075 mb and 2.77±0.28 mb were determined for the pp→pnπ+ reaction at 420 and 500 MeV, respectively. The experimental results are presented and discussed within the framework of a partial wave analysis. Theoretical predictions from a covariant one-boson-exchange model that includes final state interactions, provide a good description of the data. The pion spectra, in the region corresponding to low relative np energies, are also well described by a final state interaction model that uses the pp→dπ+ cross sections as input. Details of the determination of the background corrections and detector efficiencies will be discussed.

Polarization of Sigma+ hyperons produced by 800-GeV/c protons on Cu and Be.

The SELEX collaboration Pogodin, P. ; Alkhazov, G. ; Atamantchouk, A.G. ; et al.
Phys.Rev.D 70 (2004) 112005, 2004.
Inspire Record 629483 DOI 10.17182/hepdata.42834

We show that Σ+ hyperons produced by 800 GeV/c protons on targets of Be and Cu have significant polarizations (15–20%). These polarizations persist at values of pt≈2  GeV/c and a wide range of xF. The polarizations from the Cu target are consistently less than from Be. The average ratio of the Σ+ polarization from Cu to that from Be is 0.68±0.08.
