摘要：The next-to-next-to-leading order (NNLO) QCD analysis is performed for the virtual photon structure functions which can be measured in the double-tag events in two-photon processes in e􀀀e􀀀 collisions. We investigate the perturbative QCD evaluation of Fγ 2 􀀀x􀀀Q2􀀀P2 to NNLO and Fγ L 􀀀x􀀀Q2􀀀P2 to NLO with and without taking into account the target mass effects, which are relevant for the large x region. We also carry out the phenomenological analysis for the experimentally accessible effective structure function Fγ eff Fγ 2 􀀀32Fγ L .
