Query: Asymmetries in polarized hadron production in e^+e^- annihilation up to
  order 1/Q   We present the results of the tree-level calculation of inclusive two-hadron
production in electron-positron annihilation via one photon up to subleading
order in 1/Q. We consider the situation where the two hadrons belong to
different, back-to-back jets. We include polarization of the produced hadrons
and discuss azimuthal dependences of asymmetries. New asymmetries are found, in
particular there is a leading cos(2 phi) asymmetry, which is even present when
hadron polarization is absent, since it arises solely due to the intrinsic
transverse momenta of the quarks.
