Abstract

Spin-dependent structure function g 1 γ( x, Q 2) 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 ln 2(1/ x) resummation at low values of Bjorken parameter x. We analyse the effects of the double ln 2(1/ x) resummation on the behaviour of g 1 γ( x, Q 2) in the low x region which may be accessible in future eγ colliders.
