Approximate calculation of corrections at NLO and NNLO

A. P. Contogouris, G. Grispos

For processes involving structure functions and/or fragmentation functions, arguments that there is a part that dominates the NLO corrections are briefly reviewed. The arguments ar…

Polarized photoproduction of large-p_T hadron pairs as a probe of the polarized gluon distribution

G. Grispos, A. P. Contogouris, G. Veropoulos

Production of large-p_T hadron pairs by polarized photon on a longitudinally polarized proton towards probing the polarized gluon distribution is studied. Resolved photon contribut…
