ep - p h / 97 10 46 5 v 2 2 7 O ct 1 99 7 Can Transversity Be Measured ?

I review the ways that have been proposed to measure the quark transversity distribution in the nucleon. I then explain a proposal, developed by Xuemin Jin, Jian Tang and myself, to measure transversity through the final state interaction between two mesons (ππ, KK, or πK) produced in the current fragmentation region in deep inelastic scattering on a transversely polarized nucleon.

We review the possibility to use the renormalons emerging in the perturbation series of the twist-2 part of the nonsinglet structure functions F L , F 2 , F 3 , and g 1 to make approximate predictions for the magnitude of the appertaining twist-4 corrections.
