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
ee collisions. We investigate the perturbative QCD evaluation of Fγ
2 xQ2P2 to NNLO and
Fγ
L xQ2P2 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
