Higher twist QCD terms in high-p/sub T/ pion production

Conference ·
OSTI ID:6592448
The higher twist subprocesses qG ..-->.. q..pi../sup + -/ and q anti q ..-->.. G..pi../sup + -/ in the framework of perturbative Quantum Chromodynamics (QCD) are investigated. Cross sections for these processes are compared with the minimum twist QCD results for q anti q ..-->.. q anti q and qG ..-->.. qG. The higher twist terms give sizeable corrections to the inclusive pion yields, particularly for q anti q initial states. The effects of higher twist QCD terms for the charge ratio, N(..pi../sup -/N ..-->.. ..pi../sup -/X)/N(..pi../sup -/N ..-->.. ..pi../sup +/X) are examined.
