Abstract

Measurement of the helicity asymmetric cross section for semi-inclusive production of \ensuremathΛ hyperons in e⁺e^\mathrm\ensuremath- annihilation near the Z⁰ resonance allows a complete determination of the spin-dependent fragmentation functions for the different quark flavors into the \ensuremathΛ. The parity-violating, self-analyzing, decay of the final state \ensuremathΛ makes the experimental analysis of the helicity asymmetry possible. This experiment should be practical with present day technology at the LEP collider at CERN or at the SLAC Linear Collider.
