*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.
