*Hadron Mass Corrections in Semi-inclusive Deep-inelastic Scattering*

The spin-dependent cross sections for semi-inclusive lepton-nucleon 
scattering are derived in the
framework of collinear factorization, including the effects of masses of 
the target and produced
hadron at finite momentum transfer squared Q^2. At leading order the 
cross sections factorize into
products of Parton distribution and fragmentation functions evaluated in 
terms of new, mass-
dependent scaling variables. The size of the hadron mass corrections is 
estimated at kinematics
relevant for future experiments.
