Description
The (transverse) polarization of Lambda baryons measured in hard reactions may be described in perturbative QCD in terms of polarized twist-3 fragmentation functions. A particularly simple reaction is the production of Lambdas in electron-positron annihilation. Certain aspects of an NLO calculation for transverse spin observables in this process are discussed in this talk.
