The Q2 dependence of the flavour singlet pseudoscalar meson wave function in QCD
Description
We calculate the Q2 dependence of the flavour singlet pseudoscalar meson wave function in QCD by summing up the leading large logarithms with the aid of the ladder approximation of its Bethe-Salpeter equation. The calculation is performed in an axial gauge. We find that the Q2 dependence is diagonalized by expanding the wave function in the space of longitudinal momentum fractions in terms of Gegenbauer polynomials. The anomalous dimensions agree with those of one of the two operators to be considered for polarized deep inelastic lepton-hadron scattering in addition to the operators already contributing to the spin-averaged case.
