Abstract
We introduce twist-two quark interference fragmentation functions in h elicity density matrix formalism and study their physical Implications , We show how the nucleon's transversity distribution can be probed th rough the final state interaction between two mesons (pi(+)pi(-), K (K ) over bar or pi K) produced in the current Fragmentation region in de ep inelastic scattering on a transversely polarized nucleon.
