Query: Extracting the transversity distributions from single-hadron and
  dihadron production   We present a point-by-point determination of the valence transversity
distributions from two different types of processes: single-hadron production
and dihadron production, both in semi-inclusive deep inelastic scattering and
e+e- annihilation. The extraction is based on some simple assumptions and does
not require any parametrization. The transversity distributions obtained from
Collins effect in single-hadron production and from interference effects in
dihadron production are found to be compatible with each other.
