A measurement of the polarization of Λ and over(Λ, ̄) baryons produced in pC and pW collisions at sqrt(s) = 41.6 GeV has been performed with the HERA-B spectrometer. The measurements cover the kinematic range of 0.6 GeV / c < p < 1.2 GeV / c in transverse momentum and - 0.15 < x < 0.01 in Feynman-x. The polarization results from the two different targets agree within the statistical error. In the combined data set, the largest deviation from zero, + 0.054 ± 0.029, is measured for x ≲ - 0.07. Zero polarization is expected at x = 0 in the absence of nuclear effects. The polarization results for the Λ agree with a parametrization of previous measurements which were performed at positive x values, where the Λ polarization is negative. Results of over(Λ, ̄) polarization measurements are consistent with zero. © 2006 Elsevier B.V. All rights reserved.
