<b>Hadron Mass Corrections in Semi-inclusive Deep-Inelastic Scattering</b>
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<sup class="moz-txt-sup"><span style="display:inline-block;width:0;height:0;overflow:hidden">^</span>2</sup>. 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.</pre>
