Abstract

The importance of polarised gluons fragmenting into Λ\Lambda in the polarised e+ee^+ e^- annihilation is discussed using the Altarelli-Parisi evolution equations satisfied by the quark and gluon fragmentation functions. In this context, the polarised fragmentaion function g^1Λ(x,Q2)\hat g_1^\Lambda(x,Q^2) appearing in the cross section is discussed within the parton model. We relate this fragmentation function to the quark, anti-quark and gluon fragmentation functions and also find the QCD corrections to order αs\alpha_s.
