Abstract

We point out that the measurement of target spin depolarization D_nn in the pp → ΛΛ reaction may test dynamical mechanisms invoked to explain the proton spin puzzle revealed by polarized deep-inelastic scattering experiments. In particular, models with negatively polarized ss pairs in the proton wave function predict D_nn < 0, whereas models with positively polarized gluons would predict D_nn > 0.
