Subleading power corrections to the pion-photon transition form factor in QCD
Abstract We reconsider QCD factorization for the leading power contribution to the γ * γ → π 0 form factor F γ*γ→π 0(Q 2) at one loop using the evanescent operator approach, and demonstrate the equivalence of the resulting factorization formulae derived with distinct prescriptions of γ 5 in dimensio...
