On Experimental Studies of Λ0 Polarization

Abstract

It is well known that Λ0's are created with significant polarization in pp reactions, where both the beam proton and the target proton are initially unpolarized. But then, despite the Λ0 polarization experimental studies so far performed, the source of polarization remains elusive. To provide some light on this problem, the present experimental status of Λ0 polarization produced in pp reactions is reported and discussed.
