英文摘要	To extract the polarized gluon distribution Deltag, we study the large-p(T) light hadron pair productions in polarized semi-inclusive reaction, which are dominantly produced via 2 mechanisms: photon-gluon fusion(PGF) and QCD Compton. The PGF gives us a direct information on Deltag in the nucleon, whereas QCD Compton is background to the signal process for extracting Deltag. By using symmetry relation among fragmentation functions and taking an appropriate combination of light hadron pair production processes, we can remove an effect of QCD Compton from those cross sections. Here we propose a new formula for extracting Deltag from those processes.
