Higher Order Perturbative QCD and Non-perturbative Higher Twist Correctionto F NS 2 Structure Function

摘要

We have determined the F NS 2 structure function by means solving the DGLAP evolution equations with perturbative Quantum Chromodynamics(pQCD) corrections upto next-next-to-leading order(NNLO) using a Q2 dependent regge ansatz as the initial input. In addition we have extracted the higher twist contribution to the structure function F NS 2 in NNLO perturbative orders and then incorporated them to our results. Our NNLO results along with higher twist corrections are observed to be compatible with corresponding experimental data and other phenomenological analysis.
