Lambda0 polarization in p p ---> p Lambda0 K+ (pi+ pi-) at 27.5-GeV

The polarization of 1973 {Lambda}{sup 0}'s from the specific reaction pp {yields} p{Lambda}{sup 0}K{sup +}({pi}{sup +}{pi}{sup -}){sup 5} created by 27.5 Gev incident protons on a liquid hydrogen target, as a function of {chi}{sub F}, P{sub T}, and M{sub {Lambda}{sup 0}K{sup +}}, is, within statistics, consistent with the polarization of {Lambda}{sup 0}'s from pp {yields} P{sub fast} {Lambda}{sup 0}K{sup +} at 800 GeV.
