Abstract

We report measurements of inclusive Λ polarization, produced by unpolarized protons incident at several momenta (20, 24, and 28.5 GeV/c) onto hydrogen, deuterium, and beryllium targets. A large polarization from hydrogen, P = -0.34 ± 0.06 at pT = 1.2 GeV/c, establishes the fact that inclusive Λ polarization arises from p-p collisions.
