Observation of a difference between polarization and analyzing power in Λ0 production with 6 GeV/c polarized protons
Description
The polarization, analyzing power, and depolarization parameter were measured for forward lambdas produced with a 6-GeV/c polarized proton beam at the Argonne National Laboratory Zero Gradient Synchrotron. A sample of 15281 Λ0 production events with subsequent pπ- decays was collected. There is a clear difference between the polarization and analyzing power for events with Feynman scaling variable x greater than 0.8. This is the first observation of this phenomenon at high energy.
