Abstract

A measurement of the polarization of Λ and Λ baryons produced in pC and pW collisions at √ 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 < xF < 0.01 in Feynman-x. The polarization results from the two different targets agree within the… (More)
