QCD Factorization of Semi-Inclusive DIS Process at Operator Level**Supported by the National Nature Science Foundation of China under Grant No. 11275242

Abstract

The operator level proof of factorization theorem exhibited in [arXiv:hep-ph/1307.4194] is extended to the semi-inclusive deep inelastic scattering process(SIDIS). Factorization theorem can be proved at operator level if there are not detected soft hadrons. The key point is that the initial one-nucleon state is the eigenstate of QCD.
