Abstract: (AIP)
It is an experimental evidence that all baryons are created polarized from unpolarized p-nucleus collisions. So far, the origin of this polarization remains unexplained in spite of the experimental evidences accumulated in the past thirty years. Up to these days, 0 is the most studied baryon for polarization, for it is copiously produced in p-nucleus collisions at the energies of the principal high energy physics accelerators of the world. This paper is an overview of the experimental evidences acc umulated on the polarization of 0 from unpolarized exclusive pp collisions as function of xF, PT, and M(0K+) in the past fifteen years inside Fermilab e690 experiment, in the particular reactions ppp0K0+, pppp0 < 0, ppp0K+, produced at 800 GeV.- 25.40.-h
