We report a measurement of the x{sub F} and P{sub T}{Lambda}{sup 0} polarization dependence; {Lambda}{sup 0}{close_quote}s were produced in the specific channels: pp{r_arrow}p{Lambda}{sup 0}K{sup +}{pi}{sup +}{pi}{sup {minus}}, pp{r_arrow}p{Lambda}{sup 0}K{sup +}{pi}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}}, pp{r_arrow}p{Lambda}{sup 0}K{sup +}{pi}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}}, and pp{r_arrow}p{Lambda}{sup 0}K{sup +}{pi}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}} with 27.5 GeV/c protons incident on a liquid hydrogen target. We find that {Lambda}{sup 0} polarization is independent of the final state. {copyright} {ital 1998 American Institute of Physics.}
