QCD predictions for the spin-dependent structure function g1γ(x,Q2) of the photon in the low x region of eγ colliders

Spin-dependent structure function g1γ(x,Q2) of the polarised photon is analysed within the formalism based upon the unintegrated spin-dependent parton distributions incorporating the LO Altarelli–Parisi evolution and the double ln2(1/x) resummation at low values of Bjorken parameter x. We analyse the effects of the double ln2(1/x) resummation on the behaviour of g1γ(x,Q2) in the low x region which may be accessible in future eγ colliders.
