Abstract

We present the first data of the polarisation transfer coefficient DYY and the analysing power AY for Λ produced in exclusive channels with polarised beams. The hyperon (Y) production channels p→p → pK+Y→ have been investigated for three different beam momenta (3.67, 3.31 and 2.94 GeV/c); the results of DYY, the first available for negative cursive Greek χF, are compared with theoretical calculations in the framework of the OBE approach.
